Socals from Globware.com made an interactive demo/screensaver for the PSP called Binary v0.1. We received an email from him earlier talking about it and said I also created a demo/screensaver/simulator called Binary about a week ago but didn't really consider it news-worthy with all the new neat stuff coming out so i just it slide followed by I was mainly just writing some test code to learn new things about the PSP.
Usage instructions he provided are:
L1 = Remove Strand
R1 = Add Strand
SQUARE = Scroll Display Modes (0=Clear/1=Title/2=Title+Stats)
TRIANGLE = Toggle AUTO/FREE Mode
START = Exit to PSP
D-PAD UP = Increase Strand Speed
D-PAD Down = Decrease Strand Speed
When in FREE Mode
Analog Stick = Control all Strands
AUTO = Strands move themselves
FREE = You control their direction and speed
You can get it in our PSP Download section [here].
