Fascinating Site (planet types, etc)

[hydrozoa]

Perhaps some of you are familiar with this site:
ArcBuilder Universe that I just became aware of. Of particular interest is the page about planetary classifications

Although not Traveller-related, I found this site extraordinary. The art and ideas are IMO top notch and have already provided inspiration.

The planetary classification list is wonderful. I found it a couple years ago, and it's informed me about ways to take Traveller UWPs and suggest what those worlds might be like (Mars-like, Venus-like, Panthalassic, early Earth-stage, etc).
