When it comes to periods of art I have to admit mostly liking modern, contemporary/post modern and rococo. Not that the other periods are lost on me but modern and contemporary has the movements I love to study the most. Which ones are you interested in?
I started looking at art nouveau again after a while. I got an artbook about Alphonse Mucha not too long ago which brought it back for me. I loved how it influenced architecture as well. For me it's the organic thick lines and decorated backgrounds that attracted me to it.
I picked up a book on Futurism to understand it better. I still don't have a strong opinion on it. It was one of the influences of another favorite style of mine, art deco. My building was built during that time and the lobby is still in that style. It one of those gaudy times that it everything from graphic design to cars, but of course after times like that they get followed by a mass "toning down" of everything.
I just learned about Piet Mondrian just about a week or two ago which brought me De Stiji. (or neoplasticism?) I thought that famous abstract lines and primary colors paintings were a 1960's thing, but it was a mistake. I thought that because of Yves st. Laurent making dresses with that pattern that got really recognized.
There's tons more I say, but then this would be boarding on super blog post!
