PLplot is a cross-platform, scientific graphics plotting library that supports math symbols and human languages (via UTF-8 user input strings); plot capabilities for multiple non-interactive plot file formats and in multiple interactive environments; and bindings for multiple computer languages.

GLOBE_3D: GL Object Based Engine for 3D. GLOBE_3D is a free, open-source, real-time 3D Engine written in Ada, based on OpenGL.

Reliquarium is a unique set of four 3D geometric slider puzzles for kids, all with a Crystal Skull theme. It runs on Windows, GNU/Linux or Mac/OS-X. Reckless raiders have plundered a tomb and displaced an ancient relic. The objective is to return the relic to the center of its cubical box by rearranging the numbered blocks back into their proper order, which also represents a proper RGB coloring...Red in the X-direction, Green in the Y-direction, Blue in the Z-direction. Dragging the cursor rotates the cube for a better view angle. The mouse wheel zooms. Typing a number 1..8 selects a block to move, 0 selects the relic itself. Then use the keys {u,d,l,r,f,b} to move it. The proper command to extract the archive and maintain the directory structure is "7z x filename". These unique puzzles are spatially challenging, yet easy enough for children and will likely help with learning 3D visualization, geometry, problem solving and computer skills.

Strings edit is a library that provides I/O facilities for integers, floating-point numbers, Roman numerals, and strings. Both input and output subroutines support string pointers for consequent stream processing. The output can be aligned in a fixed size field with padding. Numeric input can be checked against expected values range to be either saturated or to raise an exception. For floating-point output either relative or absolute output precision can be specified. UTF-8 encoded strings are supported, including wildcard pattern matching, sets and maps of code points, upper/lowercase, and other Unicode categorizations.
