Here's a link to the London Eye by London DP's Ham.
Kuala Lumpur also unveiled a similar giant Ferris Wheel called Eye on Malaysia. Take a look at KL Daily Photo - Edwin's Posting of Eye on Malaysia here.
Singapore's building one too. It's called the Singapore Flyer. It is still under construction. But the base structure's up. This is how it looks like right now. When it's ready, it will be another great Singapore attraction.

Right now you have to be a bit imaginative ok? Imagine all the 32 capsules that goes on the giant observation wheel. hehe..
OK, if you can't imagine, go to the Singapore Flyer Website to have a sneak peak.
I can't wait for it to be ready and get up there! Mean time while I wait, I should go to up KL to take a ride at KL's version :-)
