Maths Shapes Can Be Dangerous

This is a very mathamatical cool hanging ornament that we have hanging from one of our windows. It is actually could be quite dangerous as the end of it is very pointy / sharp so it can sometimes be nerve wracking to walk under it.
Today I looked up at it (at my own risk) and saw that it looked even cooler than normal. As you can see in the picture there are some very faint lines which add to the pattern. These, sad to say are cobwebs , which will be taken off as it has obviously not been dusted up there for a while. But for just then it looked pretty cool.
