Seaweed is software to design and play economic-game experiments.
Seaweed can create simple two-player economic games with symmetric actions and one decision per screen. And your game is ready to be played by randomly paired people on the Internet.
An app for quickly building collections and rating them. Test at www.wudiware.com/emmaframe.php Should be good for games and communication. Lots left to add. Try the "cuteness challenge". Ideas welcome (emma should be good at idea dev. too).
