OK here’s a little goodie for everyone. Absolutely free.
This provides a GUI manipulator to rotate HDRI Skymaps.

This also includes a very low resolution HDR skymap of a single hex shaped lightsource. This is very similar to what you will find in HDR Capsule: Solo Illuminators. 
Please remember that Paralumino now has multiple options for HDRI images should you need any… www.paralumino.com
I hope everyone enjoys this!
