For this week's Photoshop Contest, I want you to take modern day gadgets and bring them back to the swinging 70s. Create retro versions of gadgets or retro ads for gadgets that didn't exist back then.

Send your best entries to me at contests@gizmodo.com with Retro Gadgets in the subject line. Save your files as JPGs, PNGs or GIFs, and use a FirstnameLastname.jpg naming convention using whatever name you want to be credited with. Send your work to me by next Tuesday morning, and I'll pick three top winners and show off the rest of the best in our Gallery of Champions. Get to it!
