The Captain’s ARK has a new front page which will allow the addition on new apps to the ARK. For now there are just two
ARK Invest – formerly called The Captain’s ARK, and
The Market Game which demonstrates how the Pareto or Power Law distribution happens with no premeditation, just as the result of random outcomes. This is the reason why it is so hard to beat the market averages. You really need some special spin on your market strategy to be in the top quartile of investors who beat the averages. The app itself could use some spiffing up! 
The Captain’s ARK is work in progress…
Enjoy!
