From Japan to SL

I introduced my customized track ball with thumbtack head for easy operation, the right button is Go-stone, the large thumbtack on the keyboard is for screen shot. Buit the left button failed. Cleaning did not help. I hesitated to buy a new one since it is expensive, but Miruru gave me a hint to use two mouses.




I put another mouse next to the track ball to use the left button only. The grayish part is a height adjuster made by sculpted eraser. It is possible to use as before. This is not useful idea since there will be no case like this^-^
