I am the author of books on 3D design (especially SketchUp) and engineering/construction (plus the occasional calendar). Many of these are also available as E-Books.
You can find and buy them here:

I occasionally design and custom print T-Shirts and other gear. While originally meant for myself, some designs may be attractive to others, too. What resulted is the small collection you can browse and buy on Spreadshirt.com.
I’ll regularly add more designs, so check back often:

Artwork and Prints
If you like a protograph on this website or on my Flickr page then chances are you can buy a printed poster or a nicely framed canvas version through Imagekind.com.
