Picture of Web Controlled Valentine
With this mix of software and hardware, you can light up a heart-adorned night light from anywhere with internet access. So whether you remember at work, in a cafe, at home, or on your (web enabled) cell phone, you can tell your valentine that you’re still remembering.
(that, or you can annoy your sweetheart by rapidly pulsing the light throughout the day, until she manually turns it off)
