"Zoetrope" is a word in ENGLISH
An optical toy, in which figures made to revolve on the
inside of a cylinder, and viewed through slits in its circumference,
appear like a single figure passing through a series of natural motions
as if animated or mechanically moved.
The Road Not TakenTwo roads diverged in a yellow wood,And sorry I could not travel both And be one traveler, long I stood And looked down one as far as I could To where it bent in the undergrowth; Then took the other, as just as fair, And having perhaps the better claim, Because it was grassy and wanted wear; Though as for that the passing there Had worn them really about the same, And both that morning equally lay In leaves no step had trodden black. Oh, I kept the first for another day! Yet knowing how way leads on to way, I doubted if I should ever come back. I shall be telling this with a sigh Somewhere ages and ages hence: Two roads diverged in a wood, and I— I took the one less traveled by, And that has made all the difference.
