Old game cant think of what it was called....

....it was a game that you were a diamond that had to make the picture. There were spider things trying to get you while making the shapes and stuff. Some of the arcade version had very poor pics of ladies. Any idea?
You had to make the picture about 80% complete before going to next level?

Sounds like QIX to me.

Spot on squarebear, although the one's with the ladies in was probably the 'Gals Panic' series by Kaneko.

Yes probably. There were loads of copies of this game but the original was Qix.
