Achievement unlocked: I've built an app large enough that it crashes my programming environment that puts all the code on a spatial surface.
The problem: I do this snazzy initial animation (see video) that takes in the whole thing before zooming back in somewhere. That animation works by drawing the whole surface to an in-memory canvas before transforming it. Turns out drawing to a canvas still uses the video card, and I don't have enough video RAM for a virtual "monitor" of this resolution.
 Or spread out enough. It's not really about lines of code, just how much area the code occupies.
