Sigh! Shouldn't people do a bit of googling before naming their project / business? This is third project with the same name. We have QuillJs[1], a rich text editor and Quill[2], an interactive grammar tool.
There's a clojure/clojurescript library for interactive drawing (layered over Processing and ProcessingJS)[1] and at least one commercial product[2] that I'm aware of. Picking unique names across languages/platforms/sectors is hard and likely unreasonable.
