Hello!

I used the parts here: http://opengameart.org/content/space-ship-building-bits-volume-1 To make a "spaceship generator" here:

http://sss-demo.site11.com/

Take a look ;) 

You can use them freely, please just credit him and send me a mail with your great project. :) 

I'd also be curious to see how it'd look like with other "pieces". So if you are a pixel artist and want to have some fun creating different ships, I'd be glad to integrate a set of parts from you in the generator to produce a different race of ships! (you can also use them for your game project or whatsoever)

Cheers,
Arnaud

PS: it's a free website and a bit slow, sorry
