Optical illusions to find on the 5th floor of Fry Hall

If you like optical illusions, Fry hall has them on floors 4 through 6.  At the entrance to most rooms, right around the door plate you can find an optical illusion.  For example, here's just a sample of what you can find on the 5th floor of Fry.

I also find the patient waiting area very inviting and the campus view is pretty cool.
