Developer sony_psp_player dropped by the QJ.NET Forums earlier to announce the release of the Function Plotter homebrew. This Lua application will enable users to plot functions on their handheld system, sort of like how you'd use a graphing calculator.

Given that there's no readme included with this release, here are its controls:

• Press select to call the osk and select to hide it.
• Press square to plot the function.
