As nxn said, IE9 is the first release with canvas support. But even there oCanvas won't work currently I think. Browser compatibility was not my highest priority before the first release. But that will be tested and improved in later releases. I have also noticed that Opera has really weird rendering on both Mac and Windows. Windows browsers in general are also a little quirky on this. But it will be tested and improved more soon.
