Can someone teach me how to make some absract art on photoshop?

google tutorials

Using some c4d render from planetrenders.net (as example)

Or use maya or any other program to make them.

To use abstract in sig, basically, you copy/paste it onto a sig, you use some blend mode, filter... And you got it.

It's way more complicated if you want to make gg abstract but if you only need the basic, that's it!

Abstract is something you need to develope on your own, just like everything else. Of course tutorials help but ultimately your just going to have to play around and find your own unique style.

If you can find a post by Shonnie, I forgot the title maybe someone can help me with this one, it has a lot of useful resources in it, particularly tutorials
