Here is the project description by Makoto:
"Plants on the earth rooted in the soil, under the command of gravity.
Roots, soil and gravity – by giving up the links to life, what kind of “beauty” shall be born?
Within the harsh “nature”, at an attitude of 30,000 meters and minus 50 degrees Celsius,
the plants evolve into EXBIOTA (extraterrestrial life).
A pine tree confronting the ridge line of the Earth.
A bouquet of flowers marching towards the sun hit by the intense wind.
Freed from everything, the plants shall head to the space."
