Hi Christopher. Not exactly the same but if you go to the shapes - say the gear or star (sorry not at my usual desk right now for screen shots) and drag that out, you can then add other shapes and select them all. Then use the Boolean operations in the top right of the screen to combine, add, subtract etc. Play around with each one so you can see. By fidddling with the shapes, number of points and all the properties and using the bool operators I was able to come up with a few different shapes once they were combined. I can try to post an example later if you get stuck. I'll be out most of the day though.
The sine etc wave generator would still be cool.
