Just a quick New Year's post to demonstrate that this blog is not dead by any means - I'm just too busy to write anything up until the end of February.
Here is a new year's picture I made together with my friend Lena. A bit of play with geometry and light.
Here is a plot of the earthquakes at the end of December, based on USGS data. I have become extremely fond of that site during the recent disaster, it is a wonderful source of up-to-date data.
