Alexander Calder had said , "To most people who look at a mobile, it's no more than a series of flat objects that move. To a few, though, it may be poetry." Calder has been my favorite artist ever since I was a kid and saw one of his mobiles hanging in a bank building. (Useless trivia: His first ever studio was in Pasadena, and the Rose Bowl Parade allegedly inspired his circus sculptures.) But to own one his pieces, I feel that you have to be 1) a millionaire and 2) have high ceilings.
After doing some digging, I found some so-so tutorials ("How to make your own Calder mobile with popsicle sticks!"), and then: smaller-scaled replicas of Calder's most iconic pieces made by Mod Mobiles for a fraction of the original price (original price being in the double-digit thousands and up).
These "mini" versions (they measure around 60" wide and about 30" tall depending on which design you want) are available at The Abstract Home.
