My first introduction to GamingMouse.com was at E3 last year. Their mouse is puck shaped, with an interesting and comfortable rubber grip running around the outside. The center of the mouse has a label area that can be customized for gaming factions or other gaming groups. This was their primary focus over the last year.
This year, they are focusing more on a four action USB foot pedal device that is fully programmable and provides additional actions of your choosing (fully mappable - including macros) that can be fired off without the use of your hands.
Also in the works is a laser version of their mouse. Check back for more information on this item; I will provide a full review of this product in the next few months when this product is production ready.
