Hey, I made it work. Hold on, I'm going to upload it now.

This is the BEST! I actually can't find a stronger engine on Phun. really. The truth.

Awesome gun dude!

you have to use the keypad, that's why

It's just because the motor goes really fast.

I love this. The one I made (not uploaded) is not sufficiently... chaotic. This is great, I will recommend this to all of my geek friends who understand chaos theory.

OMG, it changes a lot with rotating it a tenth of a degree! favoriting!

Good way of demonstrating it.

The second one does not make a heart, it makes a cardioid.

Your decorations are opaque and can't be seen- that's why it's rated down. TURN UP OPACITY FOR EVERYTHING!

This perpetuum mobile actually seems to work...
IMPOSSIBRU!

Fascinating and cool! I made another one right next to it with 15.1 rpm, and the change was AMAZINGLY high.

Amazingly cool sorter, I love it! But it does only sort by collision menu. If it could also measure by mass and size, that would be cooler.

This is a geniuses' design. You get a full 10/10. This is amazingly simple yet effective. and if you had asked me to build a weight-powered catapult with those size specifications i would tell you you had gone completely bonkers- but you did it! Wow! I love this thing!!

What really is amazing to me is that it accurately calculates sines and cosines. With only gears!

It's programmable and multiple different colors! AMAZING!

What are the rules for this turing machine? I don't have the attention span to find out!

There was this one time that two red jaws were in the "live forever" zone for a long time- and they were the last two- but when the red jaws died out, they came out and it was like BOOM!

This is fun! It works simply by gravity, and the momentum causes the 'snap' forward of the leg. That's why no other angle works- but it is still an amazing work!

I actually think your smiley is awesomer than the rest of the scene! But yeah, the scene also shows this fact well also.

I was really hoping for this to work- it is sleek and seems like it would work fast. But when I press "Enter" nothing happens.

Something in this scripting messed up Phun. Now it's broken and I can't select stuff with boxes.

Come to think of it you should have won that contest. Sorry. But it is really cool!

This was great to watch, and then when a cluster completly and utterly exploded I was mesmeriEd. 10/10 could probably watch for hours.

I don't think foreign banking should be absolutely FLOODING the bank with money, not to mention it's laggy. Your first version was excellent and this one seems nice too, but it's too laggy for me.
