TupiTube

TupiTube (also known as Tupi 2D) is a free and open-source 2D animation developed and maintained by the Colombian startup, Mae Floresta. It is available for Windows, Mac OS X, Unix-like operating systems, and Android. This project is covered under the terms of the GNU GPL-2.0 or later.

History
TupiTube originated from the KToon initiative, led by two young Colombian entrepreneurs in 2002. KToon aimed to encourage young people in Latin America to pursue animation.

Entities such as Colciencias, the Sena, and others supported the initiative during its early development years. In 2010, the KToon development team regrouped and rebranded the project as Tupi 2D Magic. Later, Mae Floresta was configured as the developer.

Features
The software includes many features:
 * Support for basic tools for vector illustration that includes rectangles, ellipses, lines, and polygons. Paths can also be created using the pen or pencil tool. The paint bucket tool can be used to fill bounded areas of vector objects.
 * Raster images (sometimes called Bitmap) can be imported and used as either static backgrounds or animated assets.
 * Finished animations can be exported to various file formats that include: OGG, AVI, MPEG, SWF. They may also be exported as a sequence of images in PNG, JPEG, or SVG format.
 * Basic support for tweaking of positions, colors, rotation, scale, sheer, and opacity has been added to recent releases.

Impact
TupiTube has gained recognition as a valuable tool for artistic education, reaching 400,000 students and being adopted by over 3,000 schools in India. The software actively participates in educational and ICT events, promoting technological education.
