this artist does't post every day, so this might be the "current" image for a couple of days

Looks like a "Calvin and Hobbes" strip.

I read this every weekend when I can. It used to be an everyday 3 panel. Now it's a weekend-only strip. Typical family topped with a young, genius son into computers and geeky behaviour.
