They were really fun days, I agree. I enjoyed them too. I remember when I bought my first block erupter at 335 megahash/sec
I thought when I bought my antminer U2's at 1.8 Gigahash/sec it would be a long while before they'd be obsolete. Boy was I wrong.
Just for fun, instead of putting out some Christmas lights this year, maybe I'll hang some block erupters and antminers in my front window and let them flash and see if 1 in 500 trillion chances I find a bitcoin block. That would be a nice Christmas present.
Do it!
