A towel is about the most massively useful thing an interstellar [desert island] hitchhiker can have. My secret santa hit the ball out of the park by sending me my very own personalized hitchhiker's towel! I won't leave home now without it :) Secret Santa also noted my interest in all things small single-board computers related and sent me a Google Voice Kit to make my Raspberry Pi talk and listen to my commands! Thanks Secret Santa and have a very merry holiday season!
