==Computata Miscellanea==
Places for homeless code snippets from the thematic project seminars and workshops.

===Script for Literal Draw/SVGs etc===
Places pixels based on an ascii grid template - an 'X' = a pixel relative to that point on the canvas, any other text character leaves a blank space.
The script expects a grid.txt argument [String], a starting x [int], and y [int] argument, a pixel size [int], and an outputfile_name.txt [string].
