This is one of the best thread I've ever seen in my life, hehe. There is so much application listed here, I've been reading for an hour yet, and I didn't read half of it, wow. I could be trying those software during a whole week, full-time, and I would not have seen half of it omg! Anyway, here is what I haven't seen listed:
Anark Studio
Not really a prog, but is IMO an awesome plug-in. Baiscally is a 3D and nicer version of the known Macromedia Flash, but for some reason a lot less known! I'm sure a lot of you know it already because they work together with NVIDIA. Check the site out and look what it can do, awesome. Check this preview of NVIDIA quadro4 :
here , WOW (of course you need to agree and install anark client, alike flash to view the content).
Copernic
Powerful search tool, I'm sure a lot of you know Copernic, it has been bought by microsoft a while ago. Allows you to search on multiple search engine at the same time, useful when you have a hard time searching the web.
Ghost mouse
You can record and playback music? Why not to the same with your mouse cursor, GhostMouse 2.0 records system-level mouse events that can be played back so the computer can execute and operate applications on its own. GhostMouse can be placed in the Windows startup group so preprogrammed tasks are carried out when Windows starts up. I use to use this program for some "macroing" in ultima online. Try this out, pretty nasty
Sorry if this was already posted but it would take me a whole day to read this thread.
