Querkles – Colour-by-Numbers reinvented
At first glance the Querkles are nothing but a seemingly random arrangement of indecipherable overlapping circles but cunningly hidden within each one is a famous face waiting to be revealed. You can keep it simple, and use one pen or pencil, or you can go colourful, with felt tips or paints: the principle is no more complicated than the colour-by-numbers books that kids love.
