There is always a bit of a mathematician in me, watching, analysing, and problem solving; especially when I make art.  In this gallery I plan to publish some pieces where mathematics was used in a crucial and clear way.  To start, I have added two drawings from the summer of 2016.  One day I was walking in the park and the most amazing impression of the soft light filtering through the leaves caught my attention.  I went home, got my colored pencils and markers, and sat myself under the tree; only to discover that the scene was way too complex to understand.

A difference bracelet consists of v beads. There are k beads of n colours and one black bead (v = k n + 1). The beads are arranged so that there are exactly λ equally coloured beads at each possible distance for every colour. The distance of a pair of beads is the number of moves to get from one to the other, either clockwise or counter-clockwise (every pair of beads has two distances). Such an arrangement is called a (v,k, λ) bracelet.
