Too much time

So, one of my little projects at the moment is trying to learn how to use Blender (the open source 3D modeling/animation package). I've been using it this term for my lectures. This is my latest creation, for my quantum 2 lectures, the first few squared spherical harmonics. I wrote a python script to draw the curves. Of course I could have downloaded an image of these and so not stayed up until 1am writing my script and so have already had my actual lecture prepared ... but where's the fun in that!
