    Exports Rocksmith 2014 arrangements to Guitar Pro tabs (.gp5, .gpx). It parses Rocksmith's .psarc archives and converts any songs found within to tablature. All the Rocksmith techniques are supported and translated, and you get all of the chord diagrams and fingering hints that Rocksmith shows you. It's a great way to figure out specific parts of a song, and Guitar Pro's speed trainer is a very good alternative to the riff repeater. All arrangement types (bass, lead, rhythm) can be exported, either together in a single tab or into separate tabs.

    Origami Editor 3D

    Origami Editor 3D

    Virtual paper folding program

    Origami Editor 3D is an advanced paper folding simulator. It uses a what-you-see-is-what-you-get interface and operates with a geometric abstraction of the Yoshizawa-Randlett system.

Origami files created with the program preserve the entire folding process, and they can be exported as folding diagrams in PDF, animated GIF files, or even as standalone Java programs displaying the origami in a 3D viewer when opened. The main purpose of this program is designing origami, but if you only want to learn how to make some origami figures, there is a set of built-in example files that can help you. Currently, there are 34 example figures available. Please note that this project was created for fun and still is a work in progress. The Discussion forum is open for anyone who wants to report a bug or suggest a new feature. User Guide: http://origamieditor3d.sourceforge.net/userguide/en/index.html
