Richard Wand just sent this lovely site around -
Make a Mixa. It's where you can create and buy your very own "1GB Flash USB drive housed inside a cassette tape shell."
I love the tagline: "undigital your digital".
Our nostalgic, rose-tinted focus has finally fallen on the humble cassette tape - that plastic, rattly, cheap, democratic object imbued with the music of our youth.
And now it comes without the reams of fiddly, degradable brown tape, so it's less likely to litter our motorways. I wonder if it still rattles? Kids these days don't know they're born.
