[Pharo-users] Block/Brick

I am trying to experiment with Bloc and Brick. I downloaded the packages, and want to "play around with it" by experimenting with the examples in it. But how do I open the examples? The github page for both Block and Brick doesn't really list much documentation. Taking from an arbitrary Brick example, these things don't work: foo := BrExamplesShowroom new. foo openInWorld. - or - BrExamplesShowroom openPlayer Sorry for the naive quesiton. - Steve PS Is Brick/Block the thing to learn these days? Is this where development is heading?
