Over the past several years, I've been lucky to work with SONOS to create a lot of the key art for their product display page.  Each product is converted from supplied CAD geometry — I then clean up the supplied geometry, texture, light, and render in Modo, and retouch and color correct in Photoshop.
In addition to the high resolution still images of each product, I also work with the UX team to create animations that are used in the Sonos app to help users setup and troubleshoot their product.
