An idea

PixCell is the common name for a couple of software pieces I made. Each piece implements a simple Pixel Art editor. The overall simplicity of the core concept makes this app a good exercise or a “weekend project”.

Common features:

  • 16x16 pixels
  • 16 colors
  • simple image transformations like “flip” and “rotate”
  • different palettes


This version is implemented in /Clojure and keeps all the state in the URL. It is a proof of concept: I just wanted to build a “thin” WebApp as a server-generated page and have no state on the server itself and also no implicit state in the cookies or other kinds of local storage. That’s why the URL keeps all the app’s state.


  • No info is storing anywhere (except for browser history), no cookies, no local storage, no user profiles on the server-side.
  • If you need to save your work you can just create a bookmark.
  • Browser history works as Undo/Redo.


This version works exclusively in your browser.

This particular version’s features:

  • Export to PNG
