We've previously written about a team of Blender users who specialize in engineering renders and animations. Their latest work has been featured on a company website as the main visuals.
The company (Brammer UK Ltd) supplies the most professional engineering parts all across Europe.
The site has many different sections, each with a series of pictures and a main animated video made by the team. Check it out here - http://www.brammer.biz/
The part sections are all on the 'home' page, select one to move to the page which holds the pictures, details and short animation about the part.
