Besides being a generally cool idea, French inventor Michel David’s volumetric display prototype gets serious wacky-contraption style points. Making a 3D image by projecting light on a spinning helical vane is not a new idea; Michel himself cites the vertical-axis FELIX 3D display for inspiration, and this 2002 paper from the FELIX 3D folks traces the technology as far back as 1958. (Thanks to Hack a Day commenter AJ for that link.)
Michel puts the cost of his machine at €40, and though his results are definitely proof-of-concept quality, I have to agree with Mike Szczys that the prototype itself “looks like a DaVinci sketch.” Can’t wait to see what the next one looks like. [via Hack a Day]
