DynaBook Junior (DBJr) is an end-user authoring system in the
tradition of HyperCard, SuperCard, and Visual Basic. If you remember
HyperCard, you will recognize the concept of a page, a background,
and a stack. Load this page in Chrome:

DBJr lets you store information freeform without the restrictions of
a database. You customize the action of a button by writing a
script. It is even possible to make games and other
mini-applications.
The world has a demo stack that explains DBJr. You can make a new stack with
$world.get("Stack").demo()
From that stack, you can use the user interface to add and delete
pages, drop in morphs of any kind, and move morphs to the background.
I built DBJr originally in Squeak, and ported it to Lively Kernel.
Many thanks to the Liver Kernel team.
