Breakthrough! The project takes several massive steps forward!
A tower structure is built by a machine. The machine is hidden from view and only the structure is seen. The structure is made from a material that resembles wet sand – actually it is sand, soil, starch and seed. Grass grows from the structure.
From under a platform, the liquid material is pumped up a tube and a mechanical device gradually builds up a tower. The material is coloured, and each ring of the tower is slightly different which reflects the surroundings at the time the ring was made. After a few days the seeds inside the material germinate and sprout. Eventually the brightly coloured towers are covered in the bright green colour of fresh grass growing from the bottom upwards.
