This is a multiplatform python script that builds on Lee's concept. It runs nice on GNU/Linux and Win32 where there's a single file executable as well. I've only tested the latter on a virtual machine though. I've written in support for mac but haven't tested it. If anyone can help, I'd be grateful. The code is licensed under the GPL and you can find it here. Some documentation exists there as well. For any questions/suggestions post here or contact me through infrael.com where I'll be selling ir pens, very soon I hope. Enjoy

Hi Maik, thanks for the feedback. I'm not sure about the cursor being off bit. The cursor reacts after mouse release or if you drag for some pixels. It's weird but quite usable. But maybe you've encountered a bug. As for the right click, when you see the cursor appear close to where you point don't release the led but move it a little. That will make the cursor come to you. Whenever you release a right click will be performed where the on screen pointer is. Could you try once more with these in mind?
