The Blub Uno Nixie Clock ($234) is from the same guys who brought you the ever popular Blub Tube Clock, but with a little twist. It uses just one tube to display the time. The numbers are displayed one after another in a natural way. It also displays the date, temperature, and comes with an alarm. Everything is controlled by either an included remote or physical buttons on the back of the case. While power is supplied by a USB port which gives multiple options for a power source. The case options include bamboo and aluminum, plain aluminum, and limited edition black. Their Kickstarter campaign is going on right now, so check them out.
