More on Amy

Amy has started praising herself; when she does something successfully, she'll occasionally say, "Good!"—perhaps because that's what we tend to say when she does so :) She'll also sometimes say "anke" (a variation of either "Danke" or "Thank you") when she does something.

Also, we're still wondering whether she's a leftie or not; while she uses both hands for some things such as feeding herself with a spoon, I have a feeling that she uses her left hand more often.

I'm going to a blood donation drive in our church's stake house. So if you never hear from me again, you'll know why :-)

Donating blood

Looks as if I survived. I still feel a bit weak, though, even after having eaten and drunk and rested a bit.

4D Rubik's cube puzzle

Rubik's cube too easy for you? Three dimensions don't really challenge you?

Try out this four-dimensional cube applet (a two-dimensional rendering [on a screen] of a three-dimensional projection of a four-dimensional puzzle).

The Crypto Rap

Edit: and a funny song about relationships using mathematical terms.
