“Orbital Flow” is a rasterized version of one of my favorite designs from 2009. I used several layers with various opacity levels to create the effects in this piece. This is probably the most elegant of the graphics you can find on this site.
Around the time this piece was created I came up with a technique to create an embossed effect in adobe illustrator. Photoshop had a great emboss / extrude filter at the time – but illustrator did not. To get around this (in illustrator cs4) I used opposite 3d-rotate transformations along with inverted opacity and complimentary layer-modes.
Basically you 3d revolve-extrude one copy of the design to the left and give it a multiply layer-mode and a black stroke. Then on top of that you use reversed revolve & extrude settings with a white stroke and a screen layer-mode.
I’m sure more recent versions of illustrator have more advanced filters – but hey if this helps someone, here’s to ya! *note: the image above is not a direct example of that technique, however it does apply several of the same methods.
