 It may happen that during propagation all the coefficients for a certain pixel become zero. That means that the algorithm has run into a contradiction and can not continue. The problem of determining whether a certain bitmap allows other nontrivial bitmaps satisfying condition (C1) is NP-hard, so it's impossible to create a fast solution that always finishes. In practice, however, the algorithm runs into contradictions surprisingly rarely.

Circles tileset is taken from [Mario Klingemann](https://twitter.com/quasimondo/status/778196128957403136). Idea of generating integrated circuits was suggested to me by [Moonasaur](https://twitter.com/Moonasaur/status/759890746350731264) and their style was taken from Zachtronics' [Ruckingenur II](http://www.zachtronics.com/ruckingenur-ii/). Cat overlapping sample is taken from the Nyan Cat video, Qud sample was made by [Brian Bucklew](https://github.com/unormal), MagicOffice + Spirals samples - by rid5x, ColoredCity + Link + Link 2 + Mazelike + RedDot + SmileCity overlapping samples - by Arvi Teikari. Summer tileset was made by Hermann Hillmann. Voxel models were rendered in [MagicaVoxel](http://ephtracy.github.io/).
