Computer Cuddle Time! Ryan's work may baffle the rest of us, but Rex under duress of a fever, was completely engaged.
I think Rex's sunglasses made the screen appear in 3-D. Who knows, but Rex wouldn't take them off all afternoon. At the least, he looked good while absorbing the subtleties of chemical reactions at the sub-atomic level.
I'm sure Ryan's work went a lot better having this cute guy on his lap. Two heads are better than one right?
