Wired offers you several ways to build your own laser, some powerful enough to burn holes in paper and other flammables but all able to ruin the eyesight of anyone you point it at ... so bear that in mind.  They range from a build claiming you need no soldering for those less technical people who want a laser to one built in an Altoids tin.  The power of the laser varies depending on the build, some even use re-purposed DVD lasers as the light source.  Perhaps the most impressive build lacks wattage but being able to project vector graphics with lasers more than makes up for it.

"Even though lasers are as common as dirt now, appearing in everything from DVD players to supermarket scanners to computer mice, there's still a certain appeal to a beam of coherent, monochromatic light. Especially if it's dangerously powerful.

So it's no surprise that people can't resist playing with lasers, building their own, customizing them and, of course, setting stuff on fire with them."
