This was on the news last week, made by an anaesthetic peer from Westmead Hospital. It was shown on Channel 7 news and the health minister was unimpressed. I think it's funny :)
LOL I thought this was cool! It's a geek eye test - some letters from famous titles as well as the typical visual acuity test - so two tests for 1! How well do you know your geek stuff?
I found it while playing with Stumbleupon. Seem to get a few referrals from there...
