otgTeX is a port of TeX Live (http://tug.org/texlive/) to the BlackBerry® PlayBook™ by David Breakey (http://www.davidbreakey.ca).
otgTeX includes the ported TeX Live code, various distributions of TeX Live built for the PlayBook, and an application written for the BlackBerry® Tablet OS Native SDK. It has translations for English and German and can easily be extended for more languages.
The otgTeX application is available on the BlackBerry® App World for a modest price. Alternatively, otgTeX can be compiled from this source for free, though it is not permitted to re-submit this app to the BlackBerry® App World without significant modification or prior permission.
