These links are only a nice version of my Mozilla SeaMonkey (former Netscape Suite)
bookmarks file, wich i have recopilated after 10+ years of using
internet,
for that reason i can't verify every one of them to be valid very often
(i only verify them only once in a while by hand), so if you find a
broken
link please tell me
and i'll actualize
it ASAP (whenever i can).
WebGL playground [beta] - An online tool for creating, testing, and sharing WebGL projects. The editor lets you work on JavaScript code and GLSL vertex/fragment shaders (if you have any) at the same time in a convenient way. You see the result on the same page. And you can use arbitrary JavaScript libraries/frameworks.
