Xplode! My first thought was what on earth am I going to do with that, but as other people have said before me, that is what these challenges are all about and Joey's challenge often stretches me which is why I like it.
I decided it was the sort of tangle which might look good drawn on a black tile. As I looked at the step out I saw there was also an aura version and so I started by dividing the tile into two aura-ed flags connected in the corner by a short pole. I then drew the original Xplode in each of the flags.
