oh man, i so remember that heart brain thing, it was from 1968 International convention. i was at the one in atlanta that lasted for 8 days. my mom took me to 6 flags over georgia the day after the convention, ultracool.
i remember counting tiles, light fixtures, empty seats, potted plants
and doing anagrams with the assembly theme name.
i remember one time i slept all the way through the main talk, that was such a blessing.
