I guess you're asking about where you can see more of the work like the blue bouncing tower?
On the Common Rotation main page
it says "Original drawings by AKGirard.com". A google search reveals that this might belong to Alexander Kori Girard, but the site is no longer working. It doesn't look there are many leads online with that name. There are a few people talking about him, but nothing for the artist. One site says he's the grandson of designer Herman Miller, but I don't know if that means in the actual bloodline sense or in the "in the spirit of" sense. There's a famous fabic designer by the name of Alexander Girard who worked for Herman Miller Designs, so maybe AK's that person's son, although none of the sites I visited for Alexander Girard mention any children. That's pretty much all I've discovered on the web.
If you click "Contact" on the left navigation bar on the index page,
you'll see a link for "17 Feet High website" which belongs to a web designer. I'm guessing this person/company took the drawings by AK Girard and created the website with them.
All pure speculation on my part, mind you. This did get me to read about Alexander Girard, so it gave me some knowledge in a subject I know nothing about. So thanks for the question.
