Speaking of crafting apps, here’s one that I’ve been playing around for the past two weeks and that’s pretty impressive. Revolved, developed by Bartosz Ciechanowski, is a $0.99 iPad app that lets you draw lines and watch them turn into 3D shapes in real-time.

Even if you don’t have any particular artistic skills, it’s just cool to play with the app and see how the split-screen layout renders lines on the right as shapes on the left. The app has been built for iOS 7, so there’s minimal interface chrome getting in the way and you can focus on your creations with controls for curves, colors, and sharing.

Seriously fun and a unique concept. $0.99 on the App Store.
