Holiday fun!

Download the postcards to make a geeky holiday greeting, or build your own RAM, ROM & CPU tree with the patterns.

Join Ruby & friends celebrating the holiday times. Maybe there is a new Hello Ruby book waiting under the Christmas tree - what better card to include than a Ruby-themed one?

Or you can cut out the hardware of the computer and assemble your own Christmas tree themed card!

Done playing?
