Right in time for the fall semester are these adjustable table legs by Ryan Sorrell.
Apparently these adjustable table legs can be clamped onto the corners of boards of varying thickness's to form a table.
The possibilities are endless with these adjustable table legs. A person could make side tables, long narrow hall tables, desks and the list goes on.
Also, the adjustable table legs can be used to change the table top based on the season and weather.
Canadian Ryan Sorrell really hit upon something interesting here.
