Graphically Speaking: I meant to get a lot of work done last night but I got sidetracked by a combination of my interest in graphic and commercial arts and my intellectual curiosity (such as it is). I spent the evening perusing some interesting sites instead, so consider this your self-indulgence alert.
Graphic Design from the 1920s and 1930s in Travel Ephemera is exactly what it says. This is the kind artistic retro advertising that I would love to have decorating my walls (yes, that makes me weird). Some of my favorites from the airlines section here, here, here, and here.
Next I stumbled across Typophile which is all about type and fonts. A seemingly esoteric topic, but really quite fascinating. I spent a lot of time fretting over the font for this site and got mildly interested in the topic. If you have some time click on the courses for a brief history of typography.
Lastly, I found the site of Edward Tufte (pronounced TUFF-tee), who has been called the Leonardo Da Vinci of data. That is to say he is exceptionally knowledgeable in the visual presentation of quantitative data. For most of us, that means PowerPoint, but there's a bit more to it than that. There's some seriously creative stuff going on in this field. Check out the ET, Writings, Artwork and News section to get a feel for things.
I told you it was self-indulgent.
