A cartoon map pack for cs_office, cs_italy, de_cbble & de_aztec does pretty much what it say on the tin
if you are interested in how this was done, all the images were batch processed on photoshop with the cutout filter and all the normals were replaced with blanks in the same manner.
there is also a dust texture set out (not by me) done in pretty much the same way, it can be found here... http://www.fpsbanana.com/skins/23662
you can find the w models & sprites etc pack at http://www.fpsbanana.com/skins/27913
