A really simple editor for generative art in JS
Press shift-space and ^.^
Live code on the left, see the result on the right.
Changes apply onChange or ctrl/cmd+enter.
You have access to the ctx for the canvas, that is it.
(But of course ctx.canvas will give you the canvas element itself.)
The bottom text input component is a label for the work of art, used to store it in localStorage.
Changing it will load whatever is at the label, or save to it if it is blank (ctrl/cmd+enter will force saving to it).
The color input component live replaces whatever selection you have in the text area with the chosen hex color of the form #RRGGBB.
The canvas size is currently fixed to 1500x500. (TODO: make configurable.)
Press on the canvas to advance frames. Shift-click to keep/stop animating, or spacebar. (Shift+spacebar to enter/leave fullscreen as well.)
