Gilrad's idea is a nice one imo... no way to get confused with keyboard buttons for the user...
Although I do enjoy the jokes of STFU and GTFO, would be confusing if someone sat there hitting the A button on the keyboard, not thinking of the buttons...
The heart, club, spade, diamond one is unique also, but seems more geared towards a gambling machine...
Personally I would enjoy telling somebody that the code is alpha and omega at the same time
