Tim with Arnold the Wonder Parrot

Here are some photos from the Computer Science Unplugged shows that were given in Christchurch and Dunedin in July 1998, and from the Kidsfest 2000 show. Click on the thumbnail to open the image in a new window.

A demonstration of binary arithmetic
Tim demonstrates how binary numbers are stored. This is based on the first activity in the "Unplugged" book, but each child holds one of the bits, which makes for much more exciting numbers.
Who'd like a chocolate fish?
The audience gets enthusiastic at the sight of chocolate. The show was primarily aimed at five to twelve-year-old children, although their parents enjoyed it too!
The parity trick
Matt and a volunteer from the audience prepare for the "Parity Trick" (activity 4 in the book), using magnetic cards.
Sorting network
Matt gets excited as an elite team of volunteers attempts to sort six disks into order in record time using a parallel sorting network (activity number 8).
The binary birthday cake
Tim wishes an audience member a happy birthday, with the aid of a specially-designed cake.
