Thanks for mentioning. I could try it on a iPhone and its obviously just way to slow to see the reaction (somewhere around 0.2 fps). Not much to do about that.

Not working on iphone OS 3.0; the initial picture & text are shown but no animation happens, also no errors reported by the embedded debug console.

“new Array” is only used at one time for the two main arrays, they are of course not always recreated (no effective processing time spent). Nevertheless I do create (with []) two 4×4 arrays for the mouse calculation (to make my code simpler) but they shouldn’t really affect a lot. I will think of a efficient way to remove them.

Worker Threads slowed it down massively (as mentioned) which is assumingly because of the memory that has to be synchronized in order to bring the picture back on the screen.

Having no iPhone I wonder if it works on the latest version, anybody tried it yet?

Worker Threads would indeed be a way to go, and a memorizing function. Also apply common JavaScript speed ups and it could become faster.

[] instead of new Array etc.
