Shader toy on iPhone

Hello all!

i saw that the shader toy app(LINK: is available for Android. Can anyone please let me know if a similar thing is available on ios?

PS: This app can be used to edit shaders on the phone!

Does a WebGL page works on iPhone ?

Thanks for the links ZBuffer! Well it seems WebGL is not supported on my OS currently(i have ios 4.2), Maybe an upgrade would do it i guess. Anyway, thanks for the links!
