The Valentine's Day contest does not ask for only recipes. From the official contest rules:To enter the contest, just publish a new Instructable before the contest ends that is in the spirit of Valentine's Day. What that exactly means we'll leave up to you. A custom dessert, an elaborate plan, a beautiful card, a piece of jewelry? It's entirely your choice. (emphasis is mine) Also, if you go and look at the entries so far you will see tatted panties, a nightlight, a footstool that looks like a Fn key, and many other entries that appear to be definitively inedible. If you want to enter your circuit in the contest, there's no reason not to.
