My friend made this. It doesn't work, but it's brilliant anyway:

the flying contraption

That's so cool. I think I'll be paying attention in Physics class now.

Very nice

Two of mine I rather like -

http://FantasticContraption.com/?designId=703936 (Four balls) - I took the longest time for this one. ;_;

http://FantasticContraption.com/?designId=745237 (Handling)

What the !?

Impressive

I managed to pathetically get to the 'Over the Hump' level but now I'm stuck. How do you make those walking robot legs? Mine failed miserably =(

Yeah, I pathetically made it to that one too, but you should be able to pathetically get over the hill the same way I did. Yay for formless blobs overcoming every obstacle.

After hours of work:

REAL MEN CLIMB AVALANCHES.

Also, my favourite solution to the over the hump problem:

For if you can't do legs.

This is fun. I still like my On a Roll solution best because it's batshit simple while others made such unnecessarily difficult things.

PS: The flying contraption is brilliant!

I couldn't get past the level where the giant ball covers the goal

Nor could I.

I finally got it, but it took awhile. Many humiliating failures. When I finally got it, it was pretty easy: http://fantasticcontraption.com/?designId=792098

No cheating though

Edit: One of my failures: http://fantasticcontraption.com/?designId=791761

That was an extremely lucky success

I just wanted to make it fly
