Roman Mars likes to tell stories. He tells lots on them on his podcast 99% Invisible which is about design and architecture. For instance, you may find those inflatable figures waving around at gas stations annoying. Mars says the creator was actually a puppeteer who made them for the opening ceremony of the Olympics. Mars also likes to wear pocket squares and drink lots of Coke Zero and ponder answers to questions like why manhole covers are round. Roman Mars talks to me about all this and the trend to disguise cell phone towers as trees.
