I've spent a fair bit of time trying to explain the WobbleWorks 3Doodler to people over the past year or so. My descriptions generally alternate between the company's slightly misleading "3D-printing pen" to "sort of like a hot glue gun that melts plastic, so you can write in the air." Makes sense, right?
