Here's one for all my pun-loving friends out there: let's make gadget ads that are fundamentally and irrevocably changed by adding, changing or dropping a single letter from the name of the device.
Send your best entries to me at firstname.lastname@example.org with One Letter in the subject line. Save your files as JPGs 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!
