Publish a copy of the current image to the ephemeric cloud:
You should see two windows opened for you:
inspector with the hostname of the published ephemeric,
remote playground with access to the image.
Now you can execute Smalltalk expressions on your published Image. For instance, if you execute ZnServer startOn: 8080 you will start a default Zinc HTTP server in the cloud and you will be able to connect to your ephemeric instance via web-browser.
