Several of my recent theme picks seem to have gone down rather well, let's try another unusual and clever theme: Aqua World. Essentially goldfish-themed, you're placed in an aquarium and with all the usual Symbian application icons and elements either fish or fern coloured and most definitely redesigned to fit in with the rest of the aquatic life in the background. All rather cute and fun... 

Here's the Aqua World theme in action:

The lock screen, working rather wonderfully dimmed, and the normal homescreen

A selection of the large selection of redesigned 'fishy' icons; colouring extends to menus (and keyboards) too...

Aqua World is a premium theme at £1.50 in the Nokia Store, so at least you can now see what it looks like before buying 8-)
