just in case you didn't want to click
It all started when a lone Japanese researcher, Shuji Nakamura, began working on developing a bright blue LED. After eight years of research the commercial blue LED was created and two years later he had developed the diode for producing a blue laser. Using gallium nitride crystals (instead of zinc selenide as many others were) he was able to solve a problem that other larger companies had been working on for many years.
Now the blue laser, with a wavelength much shorter than a red laser, is enabling the next generation of high definition DVD players to come to market. It also completes the trilogy of basic colors (red, green, blue) that are now available for handheld laser pointers.
The Blue Laser Pointer is a unique and unusual item and you can be one of the first in the world to possess this special gadget. The 473 nanometer blue laser light is sure to make all other laser pointers green with envy. It will let everyone know that you are a geek to be reckoned with, just like Shuji Nakamura.
Please note that the Blue Laser Pointer is a very new item and although it is expensive, until recently a blue laser could only be purchased for thousands of dollars. This is the newest type of laser available and as a result it's costly just as red and green lasers were when they first appeared for sale.
they also seem to have a super weak version of the novalasers alpha here http://www.thinkgeek.com/gadgets/lights/8a39/

Well, that's not true.That's a DPSS laser, not a GaN diode.And did Nakamura had anything to do with blue DPSS? :-/
You're right switch, it's not correct. That's a DPSS 473nm laser, which really has nothing to do with what Shuji Nakamura did. His work was what allowed violet, blue, and (hopefully soon) green laser diodes to be made, making direct injection lasers WITHOUT using DPSS. A DPSS blue laser doesn't use gallium nitride, so it really has nothing to do with the work for which Nakamura is famous, gallium nitride LEDs and laser diodes.
