Listen up! We're putting your song writing skills to the test. Your task is to write and record your very own geek summer hit single. You can cover any geek-related topic you like - think particle accelerators, Dr Who, trigonometry - but it must be all your own work. (You don't have to be a musical genius, but we will award bonus points if you make us laugh.)

You're encouraged to enlist the help of your entire office, science class or lab. Once you've penned your masterpiece, record it and send it to us in the form of a digital music file, You Tube video or plain old physical CD.

WHAT DO I WIN? Thanks to the donations of some awesome folks at The Economist, Deafness Research UK, Naked Scientists and Graphic Science, the top prize is nothing less than immense.

Not only will we play the winner's song, in full, on the Geek Pop podcast, we'll send you: £75 of Gadget Shop vouchers, a coveted Geek Pop Square t-shirt, 7Digital music vouchers for ten free downloads, Geek Pop pin badges for you and up to ten co-writers and an assortment of popular science books, including Poseidon's Steed by Helen Scales, a signed copy of Big Bang by Simon Singh, Crisp Packet Fireworks by Chris Smith and Dave Ansell, and the "Introducing" series books for Stephen Hawking, Time and Darwin. Oh and of course, you get a big ol' slice of glory pie. Mmm-mmmm.

PLUS! Extra prizes! The Graphic Science Most Contrived Rhyme Prize winner will receive £25 of Gadget Shop vouchers. And we at Geek Pop will award a Geek Pop pin badge to the songwriter of each valid entry.

HOW DO I ENTER? Send your MP3 file or You Tube link to crew@geekpop.co.uk or ask us for a postal address to send a CD. The deadline is 17:00 BST on 31 August 2010.

Hey, and make sure you do your homework: check out the songs we've featured previously on the podcast for inspiration, and who you need to impress to win.

Some rules:

1. Songs must not have been released, or otherwise made widely available, before the competition deadline.

2. Instruments are not essential - the prize is for song writing. So feel free to record a capella, or even get someone with superior vocal talents to sing it for you.

3. Explicit lyrics are okay, but please provide a clean or "bleeped" version too.

4. No "borrowing" from other artists.

5. The judges' decision is final. MWAH HA HA HA.

6. Bribes may be accepted, but only if they are really, really good.
