An array of colored smoke rings arrays create a 3D image in mid-air

Smoke rings can be sent for considerable distances either alone or in large arrays. Using common color toner, this device shoots layered color images into mid-air, 20 feet or more. (cross-sections of a 3D object) and thus create a 3D object floating briefly in space. The toner dissipates and ideally is biodegradable, made with natural dyes and pigments.

This is really only a new concept if defined as a 3D printer capable of producing objects viewable in the round. Incidentally there is a cool link showing that this concept could be applied underwater as well, perhaps to create 3D gelatin artwork.

Xenzag, Half Bk doesn't like long words and I can't figure out how to insert a link. You can go to my web page mallico.com and click on "colliding ring vortices" in the Technology Links.

if you click on "Link" you can paste in really long urls - try it.

We used 3d printing to make solid models in architecture school, and you can do that in color too (link) - but this idea is distinct in the scale and in the shifting, temporary nature of the image- I'd love to see how a 'printed' image would change in the wind. [+]

Bravo, [molecat]. Having experimented briefly with smoke rings as a means of detecting sound pressure levels within a room, I am heartily in favor of new uses for this technology.

One can purchase inexpensive smoke ring "guns" and appropriate non-toxic fluid in several outlets. [link]
