Charts for a classroom
A classroom wall has a specific requirement. The sheet has to be legible from the back row, and it has to be right, because thirty people will look at it every day for a term and one of them will check.
These print on ordinary school equipment: A-format paper, white background, no full-bleed colour to swallow a term's worth of toner, and every letterform converted to outlines so the file comes out the same from whatever machine is in the staff room.
The set is small, and that is not an apology. A wall with four good sheets gets read; a wall covered in them is wallpaper.

fifteen formulas · every letter explained beneath it
ANIMALS
the main branches — from comb jellies to chordates · who is actually related to whom
