Here’s a fun gadget the Green Laser Pointer II.

This pointer is significantly brighter (about 50 times) than a red laser pointer and because of its unusual color it is much more noticeable. I mean come on, a 532 nm green laser wavelength is obviously superior to a laughable 650 nm red laser wavelength. And unlike a red laser, the green beam itself can be seen in mid-air in dark conditions, not just the laser beam dot. This allows the green laser pointer to be used for pointing to star constellations (skypointing) and also just generally look cool as hell. The green laser beam dot can be seen at much greater distances than with a red laser pointer.

Here’s the specs
