New vs. Old

This is rather complicated, so please pay attention, and no talking in the back there.

What we have here is a photo of my new iMac displaying two photos side by side. Both were rotated 90 degrees to improve the composition. The one on the right is a photo of the old iMac displaying the photo on the left. You might recognize it (the photo on the right) as a previous blip. If I'd known how hard it was going to be explaining this, I might have chosen something else to blip.

Any questions?

I'll bet nobody else has done this!
