Keyboard calculator is cool. Some of the first personal computer keyboards (like the Commodore PET) used surplus calculator keys, so this is a nice reversal.

The transparent calculator is by far the best in my book. I HAD to have it! I totally agree with one of the comments, though. The transparent calculator should be a magnifier as well…it almost looks like it is…
OHH LA LA!
