My largest website is Eclectic Energies, multi-language, informative site about life energy and psychology. I designed and developed it myself (with some help from others). I wrote the lion's share of the text, and made all photos.
The site contains a translation of the I Ching, that I made from the original ancient Chinese. Especially the tests on the site, that help you get insight into your personality (chakra test and enneagram test) are very popular. Every day, about 20,000 people visit the site.
My latest addition to the site is a chatbot, that acts as a psychotherapist.
I made a website about the optical quality of glasses (Dutch), for which I did a lot of research.
My personal website is about creative things I do or have done.
