Here's JMPalm doing a 3-cascade on a high-res OS 5 Palm	And here's 534 Mills Mess in landscape mode.

Screenshots from version 1.1:

Here's JMPalm doing a 5-cascade on a black & white palm.	And here's a 5-cascade on a color palm.
This is the shuffle. Notice how JMPalm scales the pattern according to it's height.	The pattern selection screen allows you to choose from hundreds of patterns.
Any siteswap can be juggled. Common styles, such as normal, reverse and mills' mess can be selected as well.
