http://quadropolis.us/node/908 or http://quadropolis.us/node/1005?

Both of those are rather old, though. Feel free to fix them up for modern releases.

Check the attachments in Hirato's Menus, nubcake ;)

Try this: http://www.quadropolis.us/files/standalone-particles.txt
Ignore Hirato's instructions and make a file called particles.cfg, then copy and paste the script onto your new cfg and put it in your main sauer directory. Then go into your autoexec and this line: exec "particles.cfg"

Hope this helps. :)
