Over the Rainbow: playing Wizard of Oz with the Wicked Witch Spats

“Toto, I have a feeling we're not in Kansas anymore. We must be over the Rainbow!”
The main concept was to use the interactive 'magic' shoes to connect with your friend in a playful way.

Wizard of Oz is all about making new friends and discovering the old ones, friendship is the key message of the tale. If you are lost tap your shoes 3 times and a GPS signal will trigger a SMS to your friends with your location. Hope they are going to rescue you. Since the shoes couldn't fit everyone I decided to make the Wicked Witch Spats so everyone could wear it.

With the Spats you can play a locative game in the urban landscape. The play consist of minimum 2 participants: Wizard Oz and Dorothy *but more people can play. Dorothy will wear the spats and get lost around the city and with an mobile application the Wizard of Oz and the others characters are going in adventure around the city to find the lost girl. The clues with the location are going to be triggered by the spats.
