At the weekend, the lovely people at the 2015 WebWeWant festival and the Royal Festival Hall let us bring our marble runs along for parents, children, and general public to play with.
We had lots of eager helpers, buiding programs and solving challenges.
Lots and lots of creativity. Programs to sort colours, programs to reverse the order, … and programs just to look cool and make giant towers of marbles.
But what’s this? Strange symbols. We brought along some of our new code-diagramming toys too – what do you think? Do you recognise the program on the right?
