I was digging online for artwork and design ideas. One of the rpgs I used to play a long time back was Rifts, terrible system but a lot of the core imagry I always found interesting. So I set about digging up pics and ran across this gallery which is a treasure trove of rifts art. Some is kinda eh but some of his pieces are simply awesome. In particular I love his coalition designs, they really give off a nazi/imperium/evil empire feel.
A couple examples out of the hundreds of pictures he has posted.
