Dice LED decoder

Description

This little circuit decodes a three-bit input value to control a set of seven LEDs, which are meant to show the patterns on the six faces of a standard dice. Click on one of the '0' .. '6' fields of the hex-input switch to select the corresponding bit pattern, or click the '+' field to step through the input values.

(Obviously, the input value '7' is not valid for a dice, and can be considered a don't care for logic minimization. The circuit shown above enables all LEDs for this input value.)
