I created everything from scratch by using the GIMP and many of it's plugins. I tried to recreate similar texture for calimer to use inside PAS, to what was already available in sauerbraten, instead of doing my own thing. So you may, or may not notice much difference to the originals.

to use it in PAS, you'll need to modify some source files first :)

Update 1

Swapped two lensflares around, looks better now
Made lighting slightly more friendly to the blue colour channel
Used a cartoon shader on explosion.jpg. it now has a few 'holes' in it

NOTE the changes aren't reflected in the screenshot YET
