Russian designer Art Lebedev is best known in the tech world for his Optimus series of OLED and LCD keyboards (still at the pre-order stage, if you're wondering), but his eponymous studio keeps on cranking out original and quirky designs that may or may not have a chance of making it to market. Core77 noted a few of the best recent examples — top of our list is Thermosaurus, an energy-efficient cast iron radiator based on a Tyrannosaurus rex skeleton, though a publishing date of April 1st would suggest it's definitely in the "may not make it to market" column. More practical highlights include the versatile Rozetkus power adapter and the wearable Bulavkus USB flash drive that fits on to the end of a safety pin.
