I've enjoyed the amusement (my own little joke, I guess) from thinking that the fabled ABBA box is actually a special, separate machine that can be hooked up to, say, WFMU's audio equipment and broadcast. In a word, a separate "device." How would this device be designed? Well, I imagine that it's plastic and maybe yellow and orange, possibly magenta, a color combination that is bright and cheery and that I associate with the 70s. Those colors don't really reflect the two ABBA album covers I owned (sent to me by distant relatives in Sweden!), but they seem right for the ABBA device.
