What is This?

Space-age jelly? A new art installation from Jeff Koons? A scary CGI sextoy massager? Let's all pull together now, before opinions are polarized even more...

It's actually a macro photo of ferrofluid (a liquid made from nanoscale ferromagnetic particles, which can turn magnetized very quickly), shot while it's in the presence of magnets. Photographer Linden Gledhill has been exploring this extreme photography using 1.5x magnification and a StackShot automated macro rail.

Do check out the rest of Linden's photography on his Flickr page. [Flickr via Photojojo]
