A large scale (1:133) replica of St John's Beacon (The Radio City Tower) in Liverpool, UK.

Like the original tower, the letters around the circumference and the downlights light up and the tower broadcasts radio. But unlike the actual tower, this one:

 - fits on a desk,

 - has DoES Liverpool (the Liverpool makerspace) written round the middle,

- flashes the letters in a random attract mode sequence,

 - listens to twitter (@DoESTower) for colour choices on the downlights,

 - @replies to tweets with a picture and message,

 - broadcasts podcasts locally on FM radio, controlled by an RSS feed,

 - has a 3D printed, thermochromic lambanana on top!
