Just finished working on this for class:

Haha, that is awesome!

It's like an alien rollercoaster tycoon.

Is it possible to move points around? I couldn't figure that out

but it's awesome fun

Ha! Neat.

Did you ever do more of that animation you were going to make regarding the alien and his apartment and some cave with a monster?

If you read the readme file it should spell everything out for you. Basically you want to be in "EDIT MODE" (top button I think?), and then use the arrow keys to move them around. The "Y" slider adjusts each point's height. You can go out of edit mode and use the arrow keys to move the camera around.

Grismath: I've been obscenely busy between school and looking for a job. Once I graduate in December I should have lots more free time to do projects like that. I have a whole list of things that I've been wanting to do, hopefully the Mars animation will be one of them that I get done. I still like the idea of it a lot (if you couldn't already tell by the models in this program )

Not sure if it matters anymore but if you keep deleting points the program crashes.

Awesome work though. That is amazing..
