This is great, I just discovered this one, extremely simple stuff, check out the site if you didn't so far, I really like it when you hit a nice killer web app
Ok I'll talk it though quickly,
select a shape circle/cross click on the middle whiter gray box and draw, you get immediate texture in grayscale you can than click move resize, all done in a online flash application - so simple I couldn't beleive it, give me more simplicity in life
In order to save I think you have to have a registration which is for free, but you could probably just as well copy to clipboard via alt+print screen and paste it inside your favorite texture generating application, go make something I still didn't test it as a texture,
It looks so bloody simple, if you could use that kind of code to generate pattern for bump and normal maps inside octane (you can generate normals via nvidia photoshop plugin) that would be nice
Anyone got more stuff like that laying around..
