[sudo-discuss] giant laser for the robot

[Jake]

i was planning to just make an opaque, hinged privacy temporary-wall for 
when the robot is doing something dirty like that.  It will help with 
ventilation too, which is a bigger problem than arc flash with the plasma 
cutter.

but a plasma cutter is such an awesome tool, i think it's totally worth 
the annoyance of having to make it safe for puny humans.
