From the video's caption: An early example of graphics and pad usage on my ps3 version of the PSP's LUA player, using the PSL1GHT SDK and ooPo's toolchain.
To quote: LuaPlayer allows you to write homebrew in a simple language for the PS3, that doesn't need to be compiled. The new release features a GUI system, TTF fonts, and new texture support. This version brings support for TGA, GIF, and PCX textures. Currently there is no support for PNG and JPG, but it will work in the next release.
This is a little project i started for people who want to make homebrew, but do not want to get the whole toolchain and sdk set up, and for people who do not know c/c++, this allows you to create homebrew for the ps3 in a language called Lua.
