The name "echo" comes from the Greek nymph Ηχώ from Greek mythology. According to Greek mythology Echo was an Oread who had the job of talking incessantly to Hera, the Queen of the Gods, so that her husband, Zeus, wouldn't get caught in his numerous affairs. Hera caught on to Echo's trick and cursed her to only be able to say what others had just said -- hence the word "echo". Yet according to Roman mythology it was Pan, who when Echo denied his love, tore her to shreds and scattered her about the Earth leaving bits of her everywhere for us to find, or rather for us to hear, forever.

None of that has much to do with the design, yet I've discovered that if you attempt to use mythological definitions in your work people tend to take you more seriously.

Cheers.
