First, there were a couple of tense drawings.
One, two, three. At the very third second, it quickly escalated to a nonstop dry pastel scratch on A2 paper.
It then became a therapy. To release the air from the air pressure gauge.
Inflating.
Deflating.

A moment to stop sleeping and deviate towards the studio for a new set of colourful signs. Always on A2.
A moment or two, to stop looking at CAD, zoom in and out.
Plenty of moments to flip paper sheets from drafting table to floor, fighting inertia.
Colour caffeine.
