that's hilarious, i guess it would be perfect for what Trent wants to do.

make sure you get plenty of ventilation, i should have mentioned.

This can't be done in sudoroom without running a fan to the ventilation 
duct near the laser cutter.  Perhaps the clear acrylic flow-hood could be 
connected to a ventilation blower to the exhaust duct.
