He has an open playtest for a short d6 storytelling system he's created. You can check that out (and find out what it's about) here. It's a simple but fun seeming system and I know he'd like some feedback.
He has another recent project that's been getting some positive buzz. He's taking the classics, The Village of Hommlet and The Temple of Elemental Evil, and converting and adapting them to Swords & Wizardry Continual Light. Even better he's using his one page dungeon format. You folks probably realize I'm a big fan of Continual Light and have created quite a bit of content for it myself, so I think this project sounds fantastic!
So far Josh has pdfs for Monsters and Villains of the Moathouse and The People of Hommlet (and made an interesting observation about Hommlet). I'm really curious to see where this goes. I know he's done his research and is truly wanting to take the idea of this adventure and really make it focus on elemental evil.
