Another line was in comparisons, or analogies. Some were arresting … measuring data by the number of BluRay disks that would be needed to hold it, and the equivalent weight in baby elephants … the weight of iPad that could be bought for 1p … how many hamsters running in wheels it would take to power Google … . Other presentations brought up unfamiliar computing facts: the power consumption of a sleeping laptop … the rate of spread of the I♡U virus … MB versus “advertising” MB.
We saw some nice animations: using walking, running and skateboarding - or running different distances - to illustrate different rates of data transmission, as well as an animation of Wireshark. A number of groups used (sped up) drawing by hand to get ideas across. Some groups introduced themselves, while others remained behind camera commentating, or even using speech synthesis … quite a few had cheesy soundtrack music.
What were some of the memorable images and ideas? Personally I'll remember the “if a pea is one bit, then the peas in a pod are a byte”, you can get 170 Mb of data storage for 1p, and a description of how much data is in the video we're watching (script and image). We'll find out the most popular among the students this time next week, and I hope to post them on YouTube after that.
