Beethoven - Appassionata Finale as a 2D Dungeon Map (MIDI ARCHITECT CONCEPT #1)

This is a MIDI visualization idea I've been working on. It transforms a MIDI piano roll into an elaborate path unique to each piece of music. The path is calculated using an algorithm that maximizes how neatly the notes fit around corners, while rejecting turns that would cause the path to collide with itself. The aim is to create the most tightly packed and visually pleasing structure possible, so that each piece of music ends up with its own unique final construction, which is revealed at the end. Piano Sonata No. 23 in F minor, Op. 57 III. Allegro ma non troppo – Presto
