Season's greetings from matplotlib (2014). Very simple animated snow scene. (run the source, or see the result at https://www.youtube.com/watch?v=POnAkPpe770)

If working on XKCD style plotting for matplotlib taught me anything, it is that playing with software in a way that it was not originally designed to do can lead to some excellent discoveries (bugs) and generate new ideas and generalisations - not to mention it being a lot of fun!

So, in that vein, I wanted to put together a simple Christmas e-card using matplotlib. My main aim was to re-purpose some of the familiar matplotlib functionality to generate a simple festive animation.

I decided to go for a snowy scene, with a snow-capped greeting and sprig of holly. The snow is simply a scatter plot scaled by flake size and animated to fall in a pleasing way. The text is making use of the path effects functionality extended in v1.4 to add randomised "snow" around the text (the same effect employed by XKCD as it happens). And the holly is a nice demonstration of the power of Paths and vector rendering in matplotlib.

The source can be found at https://gist.github.com/pelson/ca795a02a420a1b9bfbc, and it requires m

Changes to get IPython 3 to list kernels based on conda environments (requires conda on the path, and for the post-link.sh to be executed for each IPython enabled environment). This is a hack, and I expect there is a better way of doing this...

Demonstration of constructing web map tile files. This is a useful step for static map tiles, though a further example using tornado to generate the tiles on the fly will follow - see pelson.github.io for.
