Heterochromia - a beautiful mutation of the iris.I had no idea that it was a mutation. My eyes are blue on the outsides and fade to orange around the irises. Depending on my mood and what I wear my eyes change color.
Penny Floor - don't know if I would have the patience for a whole floor. but a coffee or patio table would be nice! Also an easier way to do it is to put out the pennies then flatten then by, I don't know, maybe a broom or some thing.
