Having problems with some unfriendly Martians? Then you need the latest in Raygun Space Atomizer Technology. The Martian Blaster comes with copy machine cylinder, computer fan grill, flashlight parts and more. But if the Martian Blaster is a bit cumbersome for your needs try the Exterminator or the Buzzkill 5000, both effective in eradicating unwanted and unidentified intruders.
There loads more great retro futuristic stuff over at Electro Artworks.
