How to Sketch Your Mind in Obsidian and more, with Zsolt Viczián

TL;DR

Treat sketching as a feedback-loop system: input → organize via visuals/writing → share → iterate.

Briefing

Sketching in Obsidian—especially through Excalidraw-style visuals—works best when it’s treated as a thinking system, not a one-off decoration. Zsolt Viczián’s core pitch is that drawing and diagramming don’t merely “represent” ideas; they actively trigger understanding. When people move from text-only notes to spatial, connected visuals, they gain a feedback loop that makes relationships easier to see, revise, and reuse—turning knowledge work into something closer to performance and play.

Viczián frames the problem with text-first note-taking as a mismatch between how the brain builds meaning and how notes store it. Reading and conversation arrive as sequences of words, while the mind tries to construct relationships—often in visual form. Text can capture those relationships, but it lacks the spatial affordances of a whiteboard: the ability to place components side-by-side, move them around, and see how changes ripple through a whole structure. He argues that diagrams are especially efficient for engineering and architecture work, where understanding depends on connections, not just lists.

His approach is built around Obsidian Excalibur, a plugin ecosystem he’s been developing for years, and around a visual thinking method he calls “Sketch Your Mind: Nurture a Playful and Creative Brain.” The method centers on feedback loops: take input, organize ideas through drawing and writing, share the result, and then start again with new input. Playfulness is treated as a feature, not a distraction—visuals help people stay imaginative and productive. And instead of using visuals as a tool for isolated moments, he pushes for a systemic workflow.

A key mechanism in his system is the “hybrid note,” which combines a textual side with a visual side while keeping them linked. In practice, a note can behave like a postcard: one side compresses the idea into an image-based summary, while the other side holds the explanatory message, references, and context. Obsidian’s linking and block referencing make it possible to nest images and connect them so that editing one element updates the network. That interconnectedness creates a paradigm shift: visuals become building blocks whose relationships matter.

Viczián also emphasizes “legoized” constraints—standard sizes, limited color palettes, and card forcing functions—to reduce friction and keep visual thinking modular. Reusing consistent iconography and templates helps trigger unexpected associations, which he ties to a “serendipity machine” effect: translating abstract concepts into concrete images exposes gaps in understanding and can lead to new connections.

The conversation extends beyond note-taking into writing. He describes a visual Zettelkasten-like workflow where connected visual cards can be reorganized on a whiteboard and then flipped into a draft manuscript. While he admits it isn’t always the fastest route for him personally, the appeal is that it turns knowledge work into an enjoyable, iterative process.

For anyone starting small, his recommended next step is straightforward: when planning a project or working through a problem, open a whiteboard (Excalidraw, Miro, or similar), place the first words or sentences that come to mind, and then shuffle them until a meaningful structure emerges. The spatial act—more than the artistic quality—drives clarity.

Cornell Notes

Zsolt Viczián argues that visual sketching in Obsidian works best when treated as a feedback-loop system for thinking, not as decoration. He links drawing to cognition: moving the hand and arranging spatial elements can trigger understanding, especially because the mind builds relationships that text-only notes don’t naturally express. His “hybrid notes” pair a postcard-like visual summary with a textual back side, while Obsidian linking keeps images and references interconnected. He also stresses “legoized” constraints—standard card sizes, limited color, and forcing functions—to reduce friction and make visual components modular. The payoff is clearer planning and even faster drafting, since connected visual cards can be reorganized and turned into writing.

Why does Viczián treat drawing as more than representation—what does it do to thinking?

He frames drawing as performance: the act of moving and articulating helps trigger ideas rather than merely illustrating them. The conversation ties this to an evolutionary argument (via David G. Kirch’s concept) that thinking evolved to simulate movement and responses. In practice, sketching forces people to translate abstractions into concrete visuals; that translation exposes what they don’t yet understand, which then drives clearer articulation through subsequent drawing and writing.

What problem does “text-first” note-taking create in his view?

Text arrives sequentially, but understanding often forms as relationships. Text-only notes can store those relationships, yet they lack spatial affordances—placing ideas side-by-side, moving them around, and seeing how edits propagate. He compares this to engineering and enterprise architecture work, where diagrams communicate system structure and connections more efficiently than component lists.

How do “hybrid notes” work, and why are they useful?

A hybrid note behaves like a postcard: one side is a compressed visual (often an Excalidraw drawing or an image block reference), and the other side is the explanatory text, principles, and links. Obsidian’s block referencing and nested images let the visual and textual elements stay connected. He demonstrates flipping between sides and using shortcuts/pop-out windows so the visual summary and the detailed context remain one linked unit.

What does “legoizing” visuals mean, and what constraints does it use?

He describes three constraint types: standard sizes, color discipline, and a card forcing function. Standard sizes make components align neatly and reduce resizing friction. Limited color palettes reduce visual noise (he’s moving toward black-and-white while still using some color). The forcing function gives a bounded “sheet” for ideas, which helps prioritization and clarity—similar to how deadlines change how people think.

How does his image library support concept-building?

He prefers SVGs for scalability and reuse, though he also uses PNGs (including icons generated with MidJourney). The library is dynamically assembled via Obsidian API queries, and he uses tools like Scratchpad to recolor SVGs on the fly while preserving link/reference behavior. Reusing icons isn’t about consistency for its own sake; it’s about triggering associations and serendipitous connections when translating concepts into visuals.

How does the visual workflow connect to writing and Zettelkasten-style drafting?

He positions his method as applicable to Zettelkasten ideas without insisting on the label “Zettelkasten.” The workflow uses linked notes/cards and “train of thought” structures: cards on a topic lined up can become a rough draft. He describes a “storyboard writing machine” concept that flips connected visual cards into a concatenated markdown draft, which can then be used for further manuscript generation (including optional AI assistance).

Review Questions

When does spatial organization matter more than textual structure in Viczián’s framework, and what kind of work makes that difference obvious?
Explain the hybrid note as a “postcard” and describe how Obsidian linking changes what can be edited and reused.
What are the three “legoized” constraints (size, color, forcing function) meant to accomplish, and how do they reduce friction during thinking?

Key Points

1
Treat sketching as a feedback-loop system: input → organize via visuals/writing → share → iterate.
2
Use spatial arrangement (whiteboards) to make relationships visible and editable, not just to decorate notes.
3
Build “hybrid notes” that pair a compressed visual summary with a linked textual context so both modes stay synchronized.
4
Rely on Obsidian linking and block referencing to create interconnected visual networks where edits propagate.
5
Reduce friction with “legoized” constraints: standard card sizes, disciplined color, and forcing functions that bound where ideas go.
6
Use a reusable image/icon library to trigger associations and expose gaps when abstract ideas must become concrete visuals.
7
For planning and drafting, reorganize connected visual cards into a train of thought and then flip them into writing.

Highlights

Drawing is framed as performance—an action that can trigger understanding, not just a way to depict it.

Hybrid notes act like postcards: a visual front compresses the idea while the textual back holds message, references, and links.

“Legoized” constraints (standard sizes, limited color, card forcing functions) are used to cut resizing friction and improve clarity.

Obsidian’s linking lets images behave like connected building blocks, so changing one element updates the network.

A whiteboard-first step—placing the first words/sentences and shuffling them—serves as the smallest practical entry point into the system.
