Webcam above Kata Beach Phuket
There is currently a very good website online called See It Live Thailand. There are webcams all over the country from Phuket to Pattaya to Kanchanaburi to Koh Tao, all over! Here's a great one. This webcam is on the top of Galleri by Katathani (formerly Foto Hotel) at Kata Beach (well, not right at the beach .. the hotel is uphill a little, so you get a rather nice view!)
