This is a project that's been going on, on and off, for months now... and we finally got the light rays looking right! What we have here is a bit of a Castlevania inspired abstract 3D clock tower, with turning gears and a clock that properly tells time. You can pick from different types of clock faces and hands, and there's a few other prefs that let you control the intensity of the rays, camera motion, and so on.
The shader that's at work here is actually pretty nice, and it reacts to the silhouette of the foreground geometry quite well. We're proud of the visuals here, overall, and think other folks will enjoy them as well!
UPDATE: Just uploaded v1.01, which fixes ray occlusion on some devices!
