welp, i got that pic off his site and i'm looking at it. what i did was to sharpen it up a bit and blow it up to 200%. you can get the edited and unedited versions HERE.

what it looks like to me is that the gif is a 3D rendering of the immage in the middle on the left transitioning into the one on the botom left. the gif isnt much more legable than the blown up sharpened jpg, but you can definatly tell that the scribles inside the shelves near A and B are both "25". the x4 next to each letter i assume is to mean "four shelves".

now, what ISNT in the gif is where it shows what is labled as "Cx6". its the small rectangle between the two drawings of the shelves..it looks like its got "105" up at the top(a length?) and either "553" or "558" inside it(maybe thats suposed to be the area?).

i think two points of interest are the little squigly lines in both of the pictures of the shelves. in the first there is one(kinda shaped like a backwards C) and annother is more of the right half of a "U", and its got something written in it...kinda like a messed up 4 or something. not sure.

take a look at the blown up sharpend one and see what you think...a lot of it is still pretty un-readable.
