Art Maker Pro

On Khan Academy, a while ago, I wrote a program that would allow users to draw a picture, and then the program would generate another program which they could copy and paste and save. The new program would animate the drawing of the same picture. The program was named "Art Maker".

Recently, I created a new version of my program. The original only allowed for black and white; the new version includes color, as well as a dialog box system which I designed. The program uses only my own code - I didn't borrow anybody else's (as far as I can remember).

To embed the program on my blog, I had to use Khan Academy's script; unfortunately, their script isn't working very well here, so the program is cut off at the edge. You can access the program itself here:

I finished the program before Christmas so I could release it for everybody to use on that day... so Merry Christmas!

To use:
* Click Generate to generate a JavaScript with Processing program in the pop-up console. You can copy the program and paste it in the New Program window on Khan Academy.
* Click Undo to undo the last stroke. Click Edit to change the palette.
* Pick a color by clicking the palette.
* Hide the top bar by clicking in the upper-right corner of the canvas; show the bar by clicking in the
* upper-left corner.
* Draw by clicking and dragging. This intentionally does work when the Generate Code dialog window is open. White doubles as an eraser.
* To get past the opening screen, either wait or click somewhere on the canvas.

Keyboard shortcuts:
* Enter: Generate code
* Z: Undo
* E: Edit Palette
