BE_nSPIRED formally known as Inspired, but also known as Nspired, Nspiration, UnderTheLeaf, Clitoration and nDEAVOUR, has made many good tilesets for the NUMA community. Recently he has made the change to create playable maps but the odd n-art/tileset always seem to slip through.

Meeting him on IRC he is most likely to say.

"Guiseppi is mine! Get off him!" or along the same lines.
