Marcio C. Almeida, the developer of MACalc, has come up with a nifty port that PSP users should know very well. It's a port of Lua for use on the iPhone and iPod Touch.

This release, known as Lua v5.1.3, isn't an actual Lua port by the Lua dev team. Instead, it's a port made for personal use and distributed to the community.

Note that the downloadable file for this release doesn't come with a changelog, so Marcio has links to a couple of tutorial and reference pages for people to use while trying out Lua for their iPhone. In any case, give it a try, and see what you can make for yourself with this handy port. Enjoy!
