I overheard a song lyric that I couldn't quite make out, but sounded like "she travels by rainbow." And now the idea is stuck in my head. Not the song – I can't even recall the melody. The idea. [Update, 2008-08-10: I found the song: "Iris," by the group Hercules and Love Affair.]
I googled it ("travels by rainbow") and, except for references to that Lucky Charms Cereal spokesfairy (he travels by rainbow in his many TV appearances), all I found was a reference to a children's book and a character named Zucchini Spacestation who travels by rainbow. This is exactly the sort of children's book I could conceivably find very appealing. And it's what I was visualizing when I heard (or misheard) the lyric – a sort of wild children's story plot involving a fantastic character that travels by rainbow.
Which makes me think of the stories I used to make up for Jeffrey, about the ancient Sumerian time-traveling dogs, Enkidu and Gilgamesh, who had a multidimensional discombobulator that they used to visit other-dimensional realms, including a place called Legotopia (you can guess what that was about). Their adventures were only in the remotest way connected to the "real" Enkidu and Gilgamesh of Sumerian/Babylonian myth. Actually, their adventures probably most closely resembled Douglas Adams's Hitchhiker milieu.
Once I tried writing down some of the stories. I wonder if I still have the files saved somewhere? I know Jeffrey has a copy of one "book" that I "published" (I drew pictures and computer print-outed onto loose paper, and then bound it into a hand-made book using my rarely used book-bindery skills).
[Update 2013-06-20: I decided to add the video and lyrics. The lyrics do in fact include the phrase "travels by rainbow."
What I'm listening to right now.
Hercules and Love Affair, "Iris" ("Iris" means "rainbow" in Greek – she is the rainbow goddess).
Lyrics:
She carries news travels
By rainbow
Bearer of peace with a
Message for all
Today you'll dance,
You'll share each other
Elders will stumble,
The babies will crawlPut down your weapons, put
Down your chosen ones
Put on your best clothes,
Stand straight and tall
Don't give up on your desire,
I can understand your thirst
Put another one before yo,
Help someone else firstToday is a day for
Someone else,
Today is a day for
Someone else
Today is a day for
Someone else
This moment is yours and you
Can give it to someone elsePut down yout weapons,
Put down your chosen ones
Leave expectations at the door
You are your brother
You are your sister
Communication, start
Giving moreDon't stop believing,
Continue to give praise
Your exaltation is a good thing
Just take those teachings,
The ones of light
Of celebration, and start to sing ]
