Happy Birthday, HAL.

It would have been HAL's birthday today - he would have been either 15 (from the film) or 10 (from the book).

"I am a HAL 9000 computer.

I became operational at the H.A.L. plant in Urbana, Illinois on the 12th of January 1992. My instructor was Mr. Langley, and he taught me to sing a song.

If you'd like to hear it I can sing it for you. "

We miss you, HAL.
