I don't think that link works correctly.
Just landed in Chicago. Time to find some chow and maybe a cold beverage.

Aha, that worked.
Interesting! I can see 36 colours so it reckons I'm a tetrachromat. I like the colour yellow though.
It seems like it might depend on your computer screen more than/as much as your eyes.
I like doing colourblindness tests. Best bit of school that was.
Just an update, now I have seen the Doctor again this afternoon and had an extended ECG (keep going yer bugger - thumps chest), and it seems that I do not need a pacemaker fitted. PHEW! 
Still have an intermittent slightly less beat now and then but it is not serious.
Doctor says he is totally perplexed by the lethargy I am suffering from though and so at some point am going to have a 24 hour heart monitor strapped to my chest. Also still awaiting all the blood tests I had done.
I'm a medical mystery. 
I see 36 too - and have nothing yellow. Hmm interesting.

I can see 34 - or maybe 36. But I do like Yellow!

Bit of trivia - the most populous city in Nigeria. Not a lot of people know that. 
More Elance shenanigans?
