[This] is very cool. First, just using Legos to create an office / workgroup calendar is genius, but these folks have gone so far as to make the thing sync-able to Google’s calendar by simply capturing its image on their smart phones and emailing it to a script that parses it. *Genius!* It’s a calendaring system, an interactive visualization, and it’s Legos.
What’s better than Legos and Raspberry Pi on their own? Something that makes them work together: [BrickPi](http://arstechnica.com/information-technology/2013/05/raspberry-pi-add-on-will-help-you-build-lego-mindstorm-robots/).
[Operation: Military Kids has some great teaching materials](http://www.4-hmilitarypartnerships.org/), especially for [Lego Mindstorms activities](http://www.4-hmilitarypartnerships.org/doc12541.ashx).
[A professor worked with his son to build a supercomputer out of a collection of Raspberry Pi boards and Legos](http://arstechnica.com/information-technology/2012/09/university-builds-cheap-supercomputer-with-raspberry-pi-and-legos/). The kid is six years olds and already programming in [Scratch](). It’s time for me to start with my daughter.
Of course there’s a website where you can buy and sell new and used Legos. Why wouldn’t there be? [BrickLink](http://www.bricklink.com).
[Card reader](http://www.youtube.com/watch?v=LcwxW2ne-UU) made with Legos, Arduino, a hacked Canon camera, and Python. It images the old 80-column cards, turns the images into ASCII, and then you can take it from there. Link to Youtube video of the whole thing in action.
