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.

PS Is Brick/Block the thing to learn these days? Is this where development is heading?
