Time is all wibbly wobbly. We know this because the doctor explained it to us. Not that we understand it any better. However, this Doctor Who Gallifreyan Wibbly Wobbly Paperweight looks pretty awesome and it will look great on your desk.
It has Gallifreyan symbols on it and is a great way to keep the papers on your desk from moving around and making a mess. The design is based on the Gallifreyan sphere on top of The Staff of Rassilon.
It is just £44.99 from Forbidden Planet.
