Ever been demonstrating software, a website or some such and wanted a big pointing device to guide the audience/viewer where to look, but only had a tiddly arrow?

Here it is! Super Pointer! Drag it around the screen to show people where to look.

It doesn't work with Powerpoint. Would be interested to know if it works or not with Keynote. But for all those other demos, it should be just fine.
It also can't overlap the menubar so you'll have to use traditional methods to point to it.
