Like how there are circles and boxes there should be triangles

This would help in building

No, he means like an Object, not a mountain.

I've sometimes thought this would be a nice idea too, but the angles might get tricky.

You can't throw a triangular piece of terrain up in the air...

I've thought of suggesting it, but I imagine some work.

A triangle - what would be its properties?

I'll explain my version.

You've got your triangle, and its properties should be: velocity, size (just about all the properties of the box) but it could also be used for multiple things - it's like a wedge, but a triangle! I like it. Properties well. Make sure to make it compatible to a rocket - it would make for a rocket shuttle finishing touch!
