I love the work of Christo and Jeanne-Claude (Christo is still alive, but his companion died in 2009 – how cute is it that they have the same birth date?). The finished projects are one thing, but I also have a deep appreciation for their sketches and collages. You can read more about this sculpture that is going to be built in Abu Dhabi, United Arab Emirates, here and here.
The other day one of my students blogged about Salvador Dali and credited him for being the designer of the Chupa Chups lollipops logo. It turned out that my initial skepticism on this claim was misplaced, as it happens to be completely true! Pictured is the original design that Dali created in 1969, which has since been updated, but not deviating much from the original. You learn something new every day!
