Been teaching myself the "linear algebra" behind the "Lights Out" games.

Terrific!

I play the guitar when I feel up to it and I'm feeling it, I also play the violin and banjo but I haven't played them in a long time and I'm thinking about selling them. I used to play the drums and I guess I miss it. When I was a child I used to play the organ but haven't in ages. I can't have a piano here but I can get a keyboard someday I guess. I wish I could say I spend my time wisely but I spend far too much time wallowing and that isn't good.

I'll keep my eyes open at the goodwill for those games pods.
