The tech demo relied on a proprietary tablet-and-VR-headset combo that was eye-catching (it reminded us of something out of Tron), but commercially unavailable. Two and a half years later, the London-based startup has ditched the hardware approach entirely—but it's also a lot closer to bringing its intuitive 3D design tool to the public.

Today the company launches a Kickstarter for an app that will allow anyone to sketch in three dimensions and export their drawing to design tools like SolidWorks and Rhino or a 3-D printer. It builds on the work Gravity Sketch has been doing since 2014, and is a significant upgrade to the iPad app the company released this past March. The new app, which runs on desktop computers and either an Oculus Rift or HTC Vive, will cost $60 ($30 for Kickstarter backers) and, its creators claim, will be available beginning in January 2017.
