I like free software. Not neccessarily open source, just free

So I thought I'd start listing some of the various cool free programs that I've found and used.
Graphics Programs
I found the following page that lists heaps of free image editors, which means that I don't have to
http://www.snapfiles.com/Freeware/gm...aphicedit.html
Some others that aren't listed on that site are:
http://www.irfanview.com/
Good image viewing program. Very little editing capabilities, but has very good resizing/resampling functions.
http://www.ultimatepaint.com/
Ultimate Paint, easy to use and powerful. Shareware, basic functions are unrestricted but more advanced ones restrict saving.
http://www.cursorarts.com/ca_imffw.html
Image Forge. Some people like it, some don't.
http://www.humanbalance.net/gale/
Gale. The page is in Japanese and I've never actually used this program, but I've heard good things.
3D Modeling Programs
http://www.wings3d.com
Wings3D. I love this program. Very good modelling tool.
http://www.blender3d.org
Blender3D. One of the most popular freeware 3D animation tools.
http://www.caligari.com/products/truespace/ts3/
Calligari give away an older version of their TrueSpace software. It's pretty good.
I'll come back and add other categories and programs later. Do the same if you wish
