Today's website of the month is SIC-1. SIC-1 is a programming game based around Subleq. Subleq is an OISC (One Instruction Set Computer), in which there is only one instruction: given three memory addresses a, b, and c, subtract the value at a from the value at b, store the result to b, and then jump to the address at c if the result is less than or equal to zero. In SIC-1, your goal is to use Subleq to write increasingly complex programs, thus rising through the ranks of SIC Systems.
