iPhone app Brushes takes cues from Newton UI

When iPhone developer Steve Sprang needed interface ideas for his new painting app, he looked to a platform he knew well – the Newton.

Sprang got hold of an MP2000 in college and created the Newton freeware app, Lathe, as a simple 3D modeler. Today, he’s working on Brushes – a “natural-media style painter” that, taking a look at the screenshots, looks like a beautiful, detailed app for the iPhone (examples of Brushes-created artwork can be seen at iArtMobile).

Sprang, a former software engineer at Apple, used the Newton’s undo/redo buttons (above) in his Brushes app as a nod to his former platform. Since he left Apple, Sprang has welcomed his new role as an independent iPhone app creator.

“Developing for the iPhone has been a good experience so far,” Sprang says. “I think it’s been a great move for me, and I hope to be able to do it long term — more projects are in the pipeline!”

Brushes is available at the iPhone App Store for $4.99.
