The four seasons is a series of four pieces (spring, summer, autumn and winter) in the tradition of classic works, with the colours of each piece being an interpretation of the seasons. I used my favourite theme of Altmann’s bioblast as the motive. And it does make sense to me, with mitochondria being adaptable organelles able to supply energy to all needs and states. Winter, though, is the one that presents a kind of contradiction: the cool colours contrast with the organic forms of the confluent cells, and the sinuous shapes of the bioblasts. The final effect is rather warm.
