DIY designs for desks

The site appears to be written & designed quite poorly but the designs look quite intresting.
Of particular intrest is the In-Bed Computer Desks which lists two types, a wheeled and fixed version.
What is really good is that these are free if you are providing this equipment to people who are "Physically Challenged". Just fill in the form provided.
