WiFi Detector Ring
This is an interesting product, a wearable WiFi detector. I often have the problem in this cafe I know where I don't know what table can reach the WiFi signal. I know that the far side of the place does, but if I had this ring I could sit anywhere where the LED was on. I see that as useful, but I would only consider it if it looks like a plain silver ring, i'm not walking around like Mr. T. The image is an early prototype by the way.
