Openhouse Education is a maths tutoring centre founded by my friend, Namu. He was an actuary before having a change of heart and pursued teaching. He's not one to boast but back in the day he came first in the state in Mathematics.
He wrote a series of textbooks and asked me to design the book covers. He had an idea of a compass, a mathematical instrument with concentric circles to represent each form. Being a gig with a small budget I did an illustration and assigned a colour for each form.
