We're happy to offer some samples of the software we've developed in Smalltalk. ElasoLab is a physics-based playground that allows kids to design their own creations using simulated 2D physics. The physics of springs, elastics, air resistance and gravity are all simulated in real time.
Spider Solitaire is a card game. It's available in the Cincom Smalltalk distribution as a contributed component. You can also download it from here.
