Looking for article that was posted recently, site search has failed me.

There was an article on the frontpage about 2 days ago about an app that they were featuring that was available for the iPhone, it was a design app (not necessarily new) where you could create shapes of varying lengths and sizes- the screenshots of the designs you could make reminded me of the look and feel of the Verge logo.

I'd love to download this app and was so happy to discover it but now I'm lost at what exactly it was.

Can anyone please point me in the right direction?
