I love this Photoshop Evolution Design image!
I personally am not a Photoshop user, but it is always fun to see the Evolution of a product side by side. In this specific image from PantherHouse, it shows the Photoshop Evolution and the changes that took place with the ongoing years.
If you remember, there was also the Cellphone Evolution Video that provided images through the years from 1985 of the changes, sizes, and designs of many of the popular mobile phones many of us saw as we grew up. In addition, there is also a great History of PC Hardware given in images, that is also a lot of fun.
