Complex Bases
Numbers written in a base from the Gaussian or Eisenstein integers, every numeral of at most places one tile. Drag the base or a digit, ⌥-click to add or remove a digit, switch the lattice, take the base off the lattice altogether, roll a random system, or pick a notable system or a favorite from the caption's menu. The guide explains why one digit per residue class makes every numeral a different point.
The favorites in the menu were sent by viewers of TheGrayCuber's imaginary-bases page, which this exploration follows; each is credited as submitted there.
