So that's how you spell it...

Vroop... vroop... vroop...

According to the company that sells these, that's the noise the Tardis makes when it takes off and lands.

And that's the noise you'll hear every time you use this USB port.

[Later: OH MY GOD THEY HAVE A DALEK COOKIE JAR!!

It's out of stock, though.  Sad.]
