Nuthin' But Mech is the book from the blog of the same title. The blog was founded by Lorin Wood and has been updated regularly by a group of talented artists, of which 31 are featured here.
This 128-page paperback features a nice variety of mech designs. Many are weapon equipped mechs but there are also those for utility purposes, some animal inspired designs and two that actually play basketball. These are all original concepts from the artists. As with mech designs, there are lots of details to see.
The art is top notch. Only a handful of pages are devoted to 3D models and renders. The rest are painted, some with sketches.
The book mentioned that this is the first installment so there's more to come.
Highly recommended to those who like robots and mech designs.
