Hi, does anyone know any good tools/applications for generating textures, that could be used this weekend for the LD?

Since ALL assets have  to be made over the weekend, it makes things kinda tricky for us programmer types who are not good and fast at creating semi decent looking textures.

I have GIMP and generally know how to use the tool well enough… but that doesn’t really help me when I want to say… create a floor texture, or texture my walls in a game, or have good looking doors…

I know there are tools out there for creating procedural generated textures using noise functions, filters, patterns, etc… but does anyone have any good recommendations for these or know of any good (free) tools that could be used?

Thanks
