The visual effects in HyperCard 2.0 now work with monitors in modes other than 1 bit black and white. Monitors in 2, 4, and 8 bit modes (4, 16, and 256 colors) are supported. The visual effects will also work on secondary monitors as long as the card window does not straddle multiple monitors.
There are two visual effects added with Hypercard 2.0: stretch and shrink. Stretch appears to pull the new card image from the top, bottom, or center of the current card; shrink appears to collapse the current card image to the top, bottom, or center of its window.
