Pi plays a crucial role generating the base of the Imachinations: the wave patterns. The series of digits behind the decimal point are used little by little to define the frequency and the colour of the patterns. The human subject of the artist steps back to the favour of Pi. So the Imachinations oscillate between "irrational" calculation and accidental impression.
The latest mathematic calculations haven't found yet no regularity beyond the series of digits behind the decimal point. This irregularity of this irrational but also common number is the key for the overlaying wave layers.
