Anti-Static
--------------
Great video about static disipative and static shielding bagies from EEVblog:
<http://www.eevblog.com/2012/02/25/eevblog-247-anti-static-bag-myth-revisted/>
Summary: "pink" bags and tubes just prevent static buildup (regular bubble or
plastic wrap can generate hundreds or thousands of volts pretty easily just by
rubbing; non-conductive foam is pretty nasty too). Silver/metalic baggies
actually prevent external discharges or shocks from harming ICs inside. If you
use a shielding bag, you still need to make sure all the materials inside will
not build up a charge.

- `Entropy Key <http://www.entropykey.co.uk>`_: a $50 USB key using avalanche
noise from two P-N junctions; lots of support and features.
