Decker is a multimedia platform for creating and sharing interactive documents,
with sound, images, hypertext, and scripted behavior. It builds on the legacy of
HyperCard and the visual aesthetic of classic MacOS. It retains the simplicity
and ease of learning that HyperCard provided, while adding many subtle and overt
quality-of-life improvements, like deep undo history, support for scroll wheels
and touchscreens, more modern keyboard navigation, and bulk editing operations.
