Acrobots

Ok, love it , but just add a button to make it so your screen wont move when you move it and you can put it on and off, thank you!

It is so boring. Waste of my money. The people put 5 or 4 stars are friends of the creator or is the creator on a bunch of accounts. Really not worth a dollar.

Update 2019-works on iOS 12.1.2 awesome late night brain distraction. Update--works fine on iPhone 6+/ios8.3 . Soft, cute almost look & act alive. Lots of settings. Can't sleep? Good mindless distraction. The black background-easy on the eyes.

They act like little atoms its so cool

This isn’t really a game, it’s more of a toy. It’s great for if your bored and think “eh why not”. Very fun.

I have had this app for years and now I see it won't work with the next version of iOS unless it is updated. Often speak at conferences and I use this to relax before presenting. Please don't let it die! :-(

Very entertaining for such a simple premise: watch things bounce around. The "replay" value is apparent when you see how drastic the acrobots' behavior changes when you change a few rules (gravity, balance, stickiness, etc). This is an incredible piece of software. Any math/physics/computer science geek will appreciate what's going on behind the scenes, and anyone can enjoy just playing with it.

I love watching the little guys fly around and stick together. Perfect for relaxed fun. Definitely worth one dollar!
