Zimbabwe DollarsAs temperatures in Pittsburgh approach -20 degrees Celsius (or minus 4 degrees Fahrenheit), here are some curious news from warmer parts of the planet:

Zimbabwe is introducing a 100 trillion (!) Zimbabwe dollar note, currently worth about US$30. That's a one with 14 zeroes. This is the latest in a series of releases of new bank notes as part of Zimbabwe's fight against hyperinflation. (Pictured on the right: Its "little brother", the 100 billion dollar note).

Germany once suffered under hyperinflation as well, back in 1923. Wikipedia writes:

In 1922, the highest denomination was 50,000 Mark. By 1923, the highest denomination was 100,000,000,000,000 Mark. In December 1923 the exchange rate was 4,200,000,000,000 Marks to 1 US dollar. In 1923, the rate of inflation hit 3.25 × 106 percent per month (prices double every two days). Beginning on November 20, 1923, 1,000,000,000,000 old Marks were exchanged for 1 Rentenmark so that 4.2 Rentenmarks were worth 1 US dollar, exactly the same rate the Mark had in 1914.

Luckily, all of this is history. What remains are (now) funny pictures of people using money in unusual ways, such as wallpaper:

That reminds me, I think at some point, my family had a few high-denomination notes from the time (that are sadly still "worthless") -- I may scan and publish them if we can still find them.

For Zimbabwe, we can only hope that one day, they can look back at their old pictures and find them amusing too. For now, their political and economical situation is not enviable.

I promise, my blog is not going to turn into a "desktop wallpaper collection", but this one is too cool not to show it to you:

"Ceci n'est pas le fond d'écran officiel de Firefox / This Is Not The Official Firefox Background Picture"

By the way, the photographer Denis-Carl Robidoux publishes a picture per day, all of which in different sizes to fit your screen, and for free, too.

Just found a nice red panda pic that works as a desktop wallpaper:

I just stumbled across a collection of very nice Firefox background images.

Some of them I've seen many times (like "always wear protection", which always reminds me of the "natural mail enhancement" pic), others are new to me, but they seem to be the work of some very talented designers in the Mozilla community, so make sure to check them out.
