CamSketchpad is a modern recreation of Ivan Sutherland's seminal Sketchpad program. It's a 2D drawing and CAD program with support for geometrical constraints and the inclusion of instances referencing other drawings. It includes a very flexible geometric constraint satisfaction system based on error minimization and basic support for algebraic constraint satisfaction.
SoapQuest1024 is a small written after reading "20 Open World Games" on Gamasutra and coming across "Adventure". It's a very simple tile-based game written in 1024 lines of Java. You can wander around the place, picking things up and using them on other things by walking into them. You can save the gameand go back to it later. It's fully data-driven, based on a simple CSV format, and has things like wandering treants and a day/night cycle with light calculations.
Space exploration is a work in progress RPG. In SE, you are tasked with charting the long-abandoned Serpens Sector, a region of space reached through a wormhole near Earth. Each star system you visit brings you an encounter with something: ancient ruins, other humans, and many dangers. The map and encounters are chosen at random for each game, which means that each game plays out differently. The intention is to release the base game for free, and create expansion packs for sale.
It's not dead. No, the project isn't dead. I just have been busy with Christmas and RSI. Expect an update in a week or so.
