The UK Telegraph reports on a matchbox-sized GPS receiver / mobile phone transmitter called the Followit, which transmits its location back to its owner using SMS (mobile phone text messaging). Strap it to your dog’s collar, or tuck it under someone’s dashboard, and then sit back and keep tabs on where they go. The thing costs about 550 Euros. Spooky. Here’s Followit’s English-language home page. (via Gizmodo)
