Greetings from the Netherlands,
Ferrie
Thank you for the tip, Ferrie! What a fantastic project. I love the open source aspects and, especially, how accessible it is via the use of the Raspberry Pi. An HTML5 interface would mean near universal accessibility via any internet-connected device. I hope this project continues to develop.
