Richard Hayler wanted a way to produce Minecraft-themed birthday cards for his sons friends. So, he decided to use Minecraft Pi Edition to it! He wrote a script which takes in the name you want to generate and then pipes it into Minecraft, generating the name in 3D (see above). He then used Raspi2png to take the screenshot. He then wrote a GoogleAppEngine front-end to the whole process so that you use a web-page to enter the name and pick the block you want to use. It’s a great piece of programming with a practical use! You can read how he did it here, and download the script, or try it out yourself here (be patient!).
