Valentine's Day Card(iod)
I have to leave you with this, somewhat enigmatic, picture. It was a bit of graffiti spotted on a college campus. The photographer went to the social networking site reddit to ask what it meant... and got the answer (some NSFW language there).

If you want to see what this equation represents, then go to the Wolfram Alpha site, give it a sec to calculate, then look for the graph labeled "Implicit Plot". You'll see which one I mean pretty easily. :)

Happy Valentine's Day!
