Ripple + Gradient effects in < 1Kb

This project is only here for archive purposes.

This is the source code of my entry for the #JS1K competition (http://js1k.com/)

Generates procedural water ripple effects on top of a randomly generated gradient background. Click on the canvas to generate a new wave, hold Shift + Click to change the gradient background.

There is an issue with the Firefox canvas implementation that is a known bug (https://bugzilla.mozilla.org/show_bug.cgi?id=498826) There is no way around this issue at this time, with a test case to confirm this: http://philip.html5.org/tests/canvas/suite/tests/index.2d.imageData.put.dirty.html
