Earlier this week, I wondered if anybody was doing book trailers in a machinima format, so here's another example of a promotional video that relies almost entirely on 3-D computer animation. Digital artist Lainy Voom created nearly two minutes of "dramatic recreations of true events" which Wagner James Au wrote about in his new book, The Making of Second Life, as well as an appearance by what one presumes is Au's own Second Life avatar. The short film even gets a bit meta, as a recreation of two people conducting a cybersex affair hundreds of miles apart then zooms out into "real life," so that you're watching digital avatars watching their digital avatars engaged in virtual foreplay.

On a decidedly more low-tech note, here's a short film to promote The Undead Kama Sutra, the third novel in Mario Acevedo's series starring Iraq war vet turned vampire Felix Gomez. Watch Gomez fight off a gang of skeletal zombies, filmed with Lego figurines in all their stop-motion glory.
