Hi there, long time no nuthin'!
After the end of The Packrat comic strip early in 2015, and a few changes to my day job and residence (among other things), I sorta let umop.com lapse without a single update. This past week however I am starting a new interactive webcomic called ANYTHING COMICS! Readers can submit their own ideas for things to appear in the comic (for now these ideas are mainly going to be submitted via comments on the Anything Comics Facebook page). It's a fun new idea that you can actually help support for only $1 per month over at Patreon.
As for umop.com it was always be a giant, freely-trawled warehouse full of all the other things I've worked on since 1998, including games, free fonts, Rock-Paper-Scissors variants, electronic music, and of course lots of other comic strips!
