The joint ExPlay, Wellcome Trust, Science Museum, PM Studio games jam is due to start in few days, as the Huffington Post reports:
Not everyone can make a great video game - and even fewer can make one in less than 24 hours.
But that's just what 120 games makers are going to try and do in a few weeks, at the 2012 ExPlay Games Jam, hosted by the Wellcome Trust, Science Museum and Pervasive Media Studios.
The Games Jam - held simultaneously in Bristol and London - will give participants 24 hours to make a brand new game on a specified theme.
And yes - it has to be playable.
