The Cube Tree

 "To see a World in a Grain of Sand
 And a Heaven in a Wild Flower,
 Hold Infinity in the palm of your hand
 And Eternity in an hour."

 --'Auguries of Innocence', by William Blake

If one is curious, was there at the time, explores the tree, they may have found, are finding, did find in the past, will find in the future:

The One--A micrometaphorscopic ridge, inconsequential, between Iteration 433 and Iteration 6e6e6 of the Cube Tree, which emits a sound that brings back false memories. Shrink, baby, shrink!

Iteration 32c--A leaf, a frond, that still reminisces of the time when the Strangemusic (http://www.joshuadavis.com/portfolio_web/web_2001/shapeshifter/shapeshifter/) touched it, courtesy of Zoe
