Poly Bridge.

Poly Bridge a fun steam game people were posting gifs about on Reddit. It looked like fun so I picked it up for $12 off the Steam store. It's fun and addivictive. You guys should give it a try.

Looks a lot like Bridge Constructor, which I have on Windows Phone and Android but not desktop.

These physics games are pretty fun, though. Marked for later purchase.
