haxxy bmps is a Mastodon bot created by Serin Delaunay
This bot toots strange images full of coloured lines and rectangles, accompanied by a stream of ASCII symbols.
The patterns of lines and rectangles are generated by randomly partitioning the rows and columns, with a chance of repeating rows/pixels, or fixing a pattern so that future partitions of the same size will repeat it. The pattern of pixels is converted into a data URI containing a BMP file, which is inserted into an SVG file rendered by Cheap Bots, Toot Sweet!
The text is generated using Cheap Markovs, Traced Quick!
