A while ago I created some fun maths pictures for a competition. Now, I could either leave them to waste away on my hard drive or try and raise a smile by publishing them here.
Note that, although none of the jokes are original, the illustrations are all mine.
Maths laugh 1: Graphing the Escher staircase.
Over the next few days I will post the rest. If you have any other suggestions tweet them to me @ThomasEWoolley.
