On one end of the product design spectrum we have idiots making USB-powered sandwich warmers, i.e. useless junk that no one asked for and that hopefully does not turn a profit. On the other end we have Vestergaard-Frandsen [making] the LifeStraw, a plastic cylinder fitted with a filter that those in less developed countries can use to drink water…safely.

It’s always nice to see people using their design skills for good.
