What shape would be traced by a point on a ball rolled across a surface?
That question inspired the creation of geometry software called Engare, released last week. "It's been a while since a game made me cry simply by being beautiful," tweeted the tech culture editor of Ars Technica, a website covering news and opinions in technology, science, politics, and society.
Engare challenges players to match a target glyph by tracing shapes on progressively more complex moving objects. The software, which is part spirograph drawing tool and part game of parametric and polar mathematics puzzles, allows players to export their mosque tile-like patterns as images or three-dimensional models.
Creator Mahdi Bahrami describes his latest oeuvre as "a meditation on the dynamics of simple machines and the beauty buried deep within repeating motion." Watch trailers and game play videos, then purchase the PC or Mac OS software from the Steam platform for $6.99.
