(Tested only on nexus one, nexus s, and galaxy nexus so far. There may be many bugs, cause I haven't tested on other devices. Please let me know if it doesn't work on yours.) Use your android device as a personal CCTV. It will take and send photos periodically to your Picasa web albums, and you can browse them later. The only thing you need is a Google & Picasa account. * limits * - you may have to setup your Picasa account before use.- taken photos will have same size as your device's screen.
