Game Boy condom pack by Ben Marsh. The handheld comes with instructions (NSFW) and a variety of rubbers, each encased in a cartridge spoofing a popular game:

Ribbed - The Long End of Zelda

Heat - Dong

Tingle - Bone Zone 2

Thin - Super Mario Land of Love

X Safe - Sextris

Large - Donkey Shlong

While these are more of an art project than a commercial product, I imagine they’d work effectively as contraceptive devices, in that taking them out would kill the mood immediately. Well, unless you’re this guy.
