Could we get you to check-in the benchmark code so that we can do some additional comparisons? Great stuff, Vlad!

I got my upcoming lesson 14 working using mjs, just needed to fix one minor bug (which I've raised an issue for on the Google Code tracker). Cheers, Giles Success!

I'll try porting a few of the tutorials I've done over to it and let you know how I get on. This is an excellent idea!

I updated https://adblockplus.org/trash/orbital/index.html to use mjs, made my code simpler and works great. Only one bug report: in M4x4.rotate one might be tempted to use the same matrix for both m and r but this will produce wrong results. For some reason the translation functions are not affected by this issue. Vlad, thank you. I updated https://adblockplus.org/trash/orbital/index.html to use mjs, made my code simpler and works great.
