I used to paint but very soon lost interest. When I got back my interest, I started doing it again but with light.

Professionally I work as Signal Integrity engineer. Analyzing signals with frequency from few MHz to GHz, believed to be moving on mother boards but i cant see:-). Studying some high frequency impact. Even on weekends I do the same thing but signals are in THz frequency and fall in visible spectrum (For those who are confused THz > GHz >MHz :-)). I am happy that i can capture them, store them, share them and ask for your comments.

What you are seeing is my work on very high frequency signals :-)
