Dynamic, Interactive Creature

Now, this is an experiment I'm really proud of - because one year ago I would never have thought I could do something like this. Since then I learned everything I needed for this in Mathematics at school (actually, I also thought I would never ever need anything of the stuff I learned in Mathematics at school again^^).
So, what is this?
Actually it is just another one of my experiments. They are kinda useless but I somehow like them.
This one is a totally dynamic 2D-creature.
You can change the terrain by moving the light-grey circles up or down (wow, look! downhill-slope force! )
You can also take over control by activating the checkbox in the top-left corner (control the creature with the mouse).
Speed changes will be made whenever the creature hits the left or right wall.

I'm not sure yet how this will evolve further on, but it surely will...there are endless possibilities
