You have to install Java3d to experience this action and horror.
I got the idea for these visuals from watching a TV-program about base jumping. But in base jumping you only make one jump downwards, so I figured that would be boring, because in virtual reality you can jump up and down as much as you want. So I made it more similar to bungy jumping, where you jump up and down several times. This new extreme sport is called "Spike jumping" and I am introducing it here. This is the virtual version, and I am waiting for someone to do this in actual reality.
Watch these visuals at your own risk. I take no responsibility for what they will do to you.
