This is the OreObject SPHEREtouch mouse. It's basically an overpriced touch-sensitive ball. It doesn't matter that it's handcrafted out of steel, titanium or platinum because it still looks more like a tacky paperweight than like a mouse.
Depending on your choice of material, the SPHEREtouch's price will range from $US155 to $US255. Sorry, but all the "balls of steel" jokes in the world aren't enough to make that a decent price for an oddly shaped mouse with questionable ergonomics that doesn't even have Bluetooth.
