You don't fool me, you do also study medicine or something alike...!
If don't, congratulations, you do a perfect mix of concepts (such as the ones that will appear on my Paediatrics exam tomorrow, so I'll better finish this message and start studying).
Just to say, from now, I'm THE fan of Purple Ninja!
Brilliant work.
Thx.
PS: Purple Ninja Vs. Dyschromatopsia could be an option if you want to morph him into Blue Ninja.
