Here is a cool pen you can use to record videos on the go. It looks like a regular pen but has a built-in video camera that automatically captures HD videos or still images. You can capture up to 5 hours of AVI video at up to 1280 x 720 resolution. The pen’s camera lens is located just above the pocket clip with its microphone being on the side of the barrel under the pocket clip.
The pen has 8 GB storage space and a built-in USB port. Its battery should last for up to 2 hours. Not cheap but a neat tool to record video on the go.
