## What it is
Chalktalk is a digital presentation and communication language developed at NYU's Future Reality Lab, using a blackboard-like interface where presenters create and interact with animated 2D and 3D sketches. Sketches can be linked to demonstrate logical connections and even coded live from within the application itself.

## Use cases
- give interactive live presentations with animated sketches
- teach math and physics concepts visually on a digital blackboard
- demonstrate ideas with linked 2D and 3D animations
- live-code sketches during a talk or conversation
- build a library of reusable educational sketch objects

## When to choose
- you want an interactive, sketch-based alternative to slide decks for live teaching
- you need to animate and connect 2D/3D visual objects in real time during a presentation
- you want to write or modify presentation sketches live in JavaScript

## When to avoid
- you need polished, static slide-based presentations for export or sharing
- you want a general-purpose drawing or whiteboard app without programmable sketches
- you need a maintained tool with recent releases and active support

## Facets
- artifact type: application
- maturity: maintenance
- function: graphics, animation, interpreter, gui
- domain: education, graphics, developer-tools
- platform: cross-platform
- tags: presentation, digital-blackboard, live-coding, sketches, webgl, teaching, web-server, javascript
