"The windows are the wrong size..."

School wins TARDIS:

"The TARDIS was created by the technical team of the Museum of Science and Industry (MOSI) to promote the recent Doctor Who Up-Close exhibition. [...]  From April 9 2008 it became a permanent fixture at Newall Green Primary School after the school won first prize in competition to win it organised by MOSI."

There's a great moment in the article where the writer takes time out to describe (accurately) what a TARDIS actually is.
