Tools for the 0.2 BTC "Brave New World" puzzle

Browser tools for working on the picture and checking ideas against the published record. They need no install and no account, and everything runs on your own machine.

Picture lab

Zoom in to the pixel, split the colour channels, stretch faint marks, pull up the pale wash, flip and turn the picture, and unwrap the seal and the clock into straight strips.

Clock overlay

Lay the painted clock over the whole picture or the back of a dollar bill, move and turn it by hand, and see which labelled items land in which slice.
