PET(X) is an object manufactured for the event TEDxPrague 2017 Brave New World. It is composed of 320 PETbricks filled with red stripes cut from the used PET bottles. 20 m of red LED stripes make the X shine from the inside. The X was a stage decoration as a symbol of the event for the whole day and moved to the afterparty space afterwards. It will be used for the next TEDx events in the future as well.
