Slide-Rule Clock Will Match Your Mathcamp Trophy [Clocks]
This
clock, made by Greg Blonder from a Lego Mindstorms set, is an homage to the
slide rule. It's super simple to read; the upper rule tells the hours and
the lower tells the minutes. They move independently, and the stationary
window shows the time. This update to a retro gadget is kind of hypnotizing
to watch, even if it takes up about a foot of shelf space. As much as we
like this, we're wondering when Greg will come out with an abacus Lego
clock.
