Spotted this week (on waxy.org?), an interesting project that is creating a bunch of infographics using data from The Beatles. I especially like the lyric self-reference graphic.
A site called Check Your HUD has put together a family tree of game developers. What I like most about this is the attempt to show the relationships between the companies including: mergers, splits, name changes, and companies formed by former members of another company.
Has anyone done an update to the productions system family tree on page 19 of the Klahr/Langely/Neches book Production System Models of Learning and Development? (You may be able to view page 19 using the Google Book Preview link on the MIT Press page.)
At this point, I have gathered data on some 50+ production system tools in an effort to create an updated diagram.
To be clear, this is not a duplicate of Rolando’s BRE Family Tree. I’m tackling a very specific area: OPS variants and progeny.
However, I don’t want to waste the effort if someone has done this work already. Perhaps someone in the academic community has already done this?
