Hi BoingBoing! Inspired by this post, I went home this weekend and built this amp into a Sugar Daddy metal mini-lunchbox.

See my flickr group here http://www.flickr.com/photos/codebetter/sets/72157600224472871/

I added a on/off led to the circuit as well.

I bought the lunchbox for $1 in Target and wish I'd bought ten more. It even had sugar daddys inside!

Back in 2004, I published a windows console app that did this same thing... See here: PC LOAD LETTER was my favorite.
