Kriss and Shi introduced the co-operative Spies vs Ghosts game they had devised for the Raspberry PiRaspberry Pi Hack Day. The game is played in rooms created with a tile map so that, for every random configuration, there is always an exit to another room. Every card a player holds has a move in Morse Code and they can make moves by sending the moves as Morse Code to the Raspberry Pi. The Raspberry Pi then uses its random number generator to decide whether to make the move was successful. Killing a ghost results in a reward of jelly babies. The code is written in Lua and will run on any computer; it is available from BitBucket.
On the second Wednesday of every month they hold a gamejam, attempting to make a simple game in a few hours and release it as an opensource example of using their Game-Cake engine. A recent example is Hunted available from the Raspberry Pi store.
Shi then introduced LMMS, showing how you could start from a beat and add samples; then, by adding a counterbeat, you could it make it more complicated. You could record sounds or use the virtual piano roll to create a tune.
