I’m Adli, a current member at Hort. The link I would like to share with people is of the german artist Katharina Grosse. It was really hard for me to choose an image to accompany this article, as I love all her works. What amazes me about her as an artist is not only her use and choice of colour or the environment she sets her works in, but how she has developed and evolved the possibilities of this one simple medium over a pretty decent period of time. Enjoy her work.
I would also recommend doing a google image search on her. You will find even more great images of her work.
