Irritating marketing email

I received an unsolicited email from AMT3D offering what sounded like an interesting solution which would enable architects and developers to demonstrate to planners, etc, exactly what their new schemes will look like within the existing 3D urban environment. The email tempted me:

A demo of the Leeds pilot project can be obtained via: http://www.amt3d.com/index_files/leeds_3d.htm

However, there was no demo – just a photo of the equipment used, and an email link to request a demo. Why not link to an exciting image or short video giving me some idea of the product’s capabilities?
