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.
