For this project Tinker it! used balloons connected with a simple LED connected to a fading circuit so they faded on and off, these were hung from the roof of a building creating a ambient glowing effect during the events course and were given away at the end, and could be seen all around London that night. 120 were made for the YCN Live launch event which also featured custom RFID tags for each guest, the tags were sent out on the invitations and could be used to tag things as you explored the event, those tagged items were later sent via email to the guests mailbox.
I like the idea of using RFID to tag elements here, and the use of the balloons is some thing we are already exploring in our end of year show plans but again excites me because I love any kind of lighting control, such as this, however computer based control is more interesting.
They used a round knob fitted to podiums as an interface for content to be browsed on large screens.
