Recently BlogPress is holding a mini online contest where you can stand a chance to win a Holga camera. There are five colours for you to win, and all your need is to identify the two locations where the two photos were taken. It's actually quite easy, so I think maybe you guys might be interested.
For more info: http://blogpress.sg/2009/11/holga-ca...ay-on-5-blogs/
I think the eligibility is that you have to be based in Singapore (PR, citizen, foreigners all can participate, when I emailed the organizer) and have to be in person to collect the Holga camera yourself.
p/s: Of course be rest assured that I'm not paid to write this I'm the owner of one of the site organizing the contest and I'm guessing that you guys might want to win the Holga camera
