I found out about these über cool lampshades months back on the Looks Like Good Design blog. Bought myself a couple and have been getting a lot of comments from friends ever since. Based on what they told me in a quick email exchange, this micro business of lamp shade design is something of a happy accident. Graphic design is their primary trade. Lets hope they keep up with the product design route. They seem to have a knack for it.
