Lately, he's been making book collections of the entire run of daily strips available at Lulu.com.* When complete, the dailies will fill fifteen books altogether.
Mr. Grace also sells originals of his comic strips. Details on how that works, here. I've bought a few of the original strips and several of the books.
He recently posted three videos of himself making a mask, Part 1, Part 2, and Part 3 on his blog. My mother saw that and sent him a link to our video (see comments in Part 1), which he mentioned on his blog on Sunday.
*Hmm. Looks like Lulu's recent re-design has goofed up the book cover images on the site, including my own. They're probably working on fixing it. I'll check my account.
