I haven't seen much about this... even Google only comes up with 65 results. Thanks to
Towleroad for turning me on to it.

A new series of Swiss Banknotes features a microscopic picture of the AIDS virus. The Swiss National Bank intends to introduce the new series by 2010. Eariler this year, twelve designers were invited to submit designs representing "Switzerland open to the world". You can see the entire slate of winners
here. The designs could not represent individuals, inventions or achievements.
Not everyone is happy with the designs.
Since my first visit to Switzerland in 1999, I have always thought their money was some of the most georgeous in the world. Indeed, the rest of the world makes our currency look entirely hum-drum and boring. So why not make it cutting edge? I would expect nothing less of the Swiss. Perhaps handing over a bill depicting the AIDS virus after enjoying dinner with friends will remind people of the unseen and unspeakable horrors that many think have gone away.
