Maximeroz has an excellent HDRI pack available for free.

Here are a couple of test renders I did of the new physically-based hair shader coming in Arnold 5. Model and groom courtesy of Zeno Pelgrims.

MAXtoA Version 0.9.608 is out. More information here.

Saber Jlassi has created some incredible pyro simulations, rendered with Arnold for Houdini.

He also has a youtube channel with Arnold rendered pyro animations.

Thrilled to see my colleagues at Solid Angle win a Science and Engineering SciTech Oscar award. More information  below:

Zeno Pelgrims has updated his camera shader for Arnold. It is capable of simulating optically imperfect lens effects.

Here is a simple test using the alHair shader to create some hair for a Barbie doll. Simply reducing the Melanin and Highlight width gives a more realistic result.

Many thanks to James Busby from Ten 24 for this article about some of my work with Arnold using their scans.
