Tree vs. Tube design

This is old news, but I like the image so much that wanted to share it. John Coulhart designed a variation on the classic depiction of the ten Sephirot. It is using the look and feel of the well-known map of the London underground system. He made the design available on CafePress, a company which prints your design on mugs, t-shirts, sweaters and other objects. However CafePress pulled his item, because the “Transport for London provided [them] with a notice stating that the use of the London Underground Roundel infringes upon their intellectual property rights.” So the artist reworked the piece. I still think it looks fun. But if Kabbalah is esotericism, i.e. a hidden art, then isn’t it a bit counterproductive to ware it outside?
