I need help. What is name of this controller ?

Thank you very much.

I'm guessing this picture didn't just appear out of thin air. Any additional information you might feel like sharing would make it more likely that you'll get a useful answer.

It appears to be a 16 stepper motor driver board. The text in the corner of the board says "Serial Stepper Controller 16".

That's right.

Thanks PaulRB.

Do I win a prize? Why did you ask the question if you already knew the answer?

Pretty impressive looking. I guess if you make a mistake a blow out one of the stepper drivers, you are looking at a very expensive replacement! I rather like the little individual stepper drivers that seem to be all the rage for 3d printer apps:

Looks like it's from the 800+ motor Sculpture: Daniel Rozin’s interactive sculpture is made of 832 moving tiles - The Verge See also Daniel Rozin Interactive Art
It seems to be what he does. Alas, I don't see anything that causes me to believe that this is a commercially available board that anyone can buy (but it looks like he goes through a LOT of them!)
