A while back I was hanging out with Christa's family, and whenever the nieces and nephews are around we do art. For some reason that day we made masks. This is my Einstein mask. I'm posing in front of Christa's sewn paper wall piece with my "memory ray gun" which I made using paper bags, toilet paper rolls and old photos. You aim the ray gun at something (visible or imagined) that you would like to remember more or less vividly and press "enhance" or "fuzz" on the gun. Imagination exercises do help retrain a part of your brain that can atrophy if you let it.
And it's kind of fun.
