Andy Balaam shows you how to make your own e-card, with a pretty snowflake animation. We will use Scratch, which you can get on a Raspberry Pi, but you can also use it on most other computers. Download Scratch from http://scratch.mit.edu/ . More details here: http://www.artificialworlds.net/blog/2014/12/16/snowflake-christmas-card-in-scratch-on-the-raspberry-pi/
