You're talking about ReadyArt (deviantArt page can be found at
http://readyart.deviantart.com/). The series in particular is called "Packing" (believe it was an interim release between Growth Lab #5 and #6). It's actually good timing because he's just starting the release for Growth Lab #7.
He archives all of his stuff between his main Yahoo! Groups page at
http://groups.yahoo.com/group/readysart/.
Cheers!
