Sparks dynamic animation (sparks movement affected by cursor position and "fluid density")

The sparks movement is affected by the displacement of the cursor when moving along XMB columns and rows (left-right, or up-down directions). When the cursor moves fast to a new position the sparks "tends" to move in the opposite direction trying to mimic a real fluid like air or water

To see this effect is good to configure a black wallpaper and enable all the options iside "theme settings" to "original" (this will make the sparks very visibles). Then start moving the cursor from left column (user) <---> to right column (friends)... or from top item <---> to bottom item in any colums (more visible in a column with several items, like game)... and note how the sparks directions are affected :)

This proves the sparks is a dynamic animation, is constantly "reading" the position of the cursor to adjust particle directions

wallpapers After extraction, the 24 .dds images used as wallpapers shares the same header (0x80 bytes), after the header starts the pixel info (each pixel is 4 bytes length in RGBA format). Is posible to change the pixel info without changing the header

00 00 00 FF = black pixel

Tools

QGL

• this tool can decompress a QRCC to QRCF and compress a QRCF to QRCC

https://raw.github.com/wargio/ps3tools/master/QGL.c (just run make to compile it)

DDS

• This tiny tool can extract embedded .dds, heavily based on an MPO splitter by Christian Steinruecken.
