I currently have two main software projects — a PPC port of IsForth and a PPC assembler. The assembler is still in the planning stages. I hope to put the good features of Forth into an assembler. That is, I'm aiming for an extensible, interactive assembler.
I'm also in the process of building a full-size air-hockey table. This grew out of my dissatisfaction with the toy air-hockey tables that are commonly available. They tend to be fragile, the bumpers don't bounce well, and the puck doesn't glide with that eerie smoothness. So I'm attempting to design something that will have reasonable performance, and could be built by anyone, with basic tools and for a reasonable price.
