Chess Pieces for a online game -- multiple prizes

Looking for original chess piece designs to use as part of an online game. Pieces can be conventional or quirky, plain or themed; I don't have a totally fixed idea of what I'm looking for, so surprise me!

The prize for this contest is $150, but there can be multiple winners - I'll pay the full prize amount for each set I like.

I'm looking to have some original and interesting sets of pieces designed to use with an online game, so that players can choose from a good range, to suit their tastes or usability preferences.

Chess pieces are nominally black and white, but you don't need to stick slavishly to that - pieces that use a different two colors may be okay, as long as they have sufficient contrast (ie. one quite dark and one quite light), or you can use multiple colors or spot colors. 

I'm interested in pieces that look quite traditional or conventional. Also interested in pieces that are quirky or unusual, or follow a theme such as Sci-Fi or D&D.

Submitted image sets should be in 24-bit PNG format, at two sizes: 70x70 and 35x35

For reference, in case you don't know what chess pieces look like -- http://en.wikipedia.org/wiki/Chess_piece

- original and unique designs; something a little out of the ordinary

- no violent or adult-only themes (but mild horror/gothic is okay)
