In the picture I have tried to portray what would at first appear to be a dichotomy in meaning but which is really a matter of perspective.
"Infinity Bound":
. A vast unlimited ever expanding playground, a never ending laboratory to explore and categorize. Humanity is uncovering ever more limitless environments. Humanity is bound for infinity.
.Infinity is even more restraining than physical bars. They fix us just as firmly into a physical space. The difference being that they appear like the proverbial pot of gold at the end of the rainbow; no matter how far you go they are still out of reach. More importantly you can never break free because you can never reach them in the first place.
