Hi, I am Jo, and I created Solitr in November 2011.
I would like to thank Richard Hoelscher, who created an excellent vector version of Grimaud's 19th-century "Paris pattern" card deck (see the archived page or download paris.svg).
Get in touch with me at [email protected], or follow me on Twitter at @jo_liss.
Let me know if something doesn't work. I also love hearing suggestions!
