This working pen is ridiculously awesome, if you believe the uncorroborated early reports:
• At under 6 inches long and just a half inch thick, it records 320x240 video at 30fps, even in low light. • You can set it to start recording video when it detects motion, or recording audio when it hears a sound. • It takes MicroSD flash cards, and can transfer video wirelessly via Bluetooth. • You can program it to send an alarm wirelessly to a "remote location".
