The Russians do absolutely the coolest things off-road vehicle-wise.
There is a company that still makes the triamgular tracks that replace your tires.http://www.mattracks.com/I have a good friend who bought a set for working on his farm in the winter. They work very, very well.
Sno-Cat, anyone ....?Seems to me like there was an outfit back in the seventies that was making a set of four "triangular" treads that you could bolt right up to a four wheel drive This allowed "normal" steering with the front axle.
A friend has one of these:http://www.snow-hawk.com/model_home_snow-hawk_800ho.aspx
