bored of base 10? how about
The BitField Contraption:
The bitField contraption (shown here linked to an ordinary field widget), stores a numeric value and allows it to be viewed and edited as binary digits. Clicking toggles a bit, and dragging can set multiple bits quickly. The "width" (in bits) can be configured to any value between 1 and 32. Like a Field widget, it fires an "on change" event, and it respects the "show", "font", and "locked" common attributes.
