Software for Generating Origami Diagrams
This isn't a gift idea, but it is related to computers, so we list it here:

• Doodle: by Jérôme Gout, Xavier Fouchet, Vincent Osele, and volunteers. Uses ASCII code to generate origami diagrams. See samples here.
• Fold A Face by Hans Dybkjær. an interactive computer program which allows you to pick facial features to be folded into a piece of paper. You can choose ears, eyes, mouth, and color for your origami face.
• Interactive Ring Tessellation by Robert Lang. An interactive demo that displays a tessellation and its folded form for a "Rings"-type tessellation. You can adjust several controls that affect the crease pattern and then see the results in the folded form in real time.
• ORIPA: by Jun Mitani. Generates crease patterns. See demo on youtube.
• Ori-Revo: by Jun Mitani. A design tool for the purpose of exploring new origami models based on "surface of revolution" shapes.
• Rigid Origami Simulator by Tomohiro Tachi. Simulates kinematics of rigid origami from .opx or .dxf crease pattern. See samples here and here.
• Tabula by Is a dynamic geometry program which allows you to manipulate images including the appearance of folding paper to form crease lines. It is a learning tool to virtually cut, tape, fold, measure, and transform geometric figures. Watch video to see its purpose.
• Tessellation from a Square Twist Fold: by Ben Kraft. Software simulates "square twist" motion.
• TESS: by Eric Gjerdi and Alex Bateman. Generates origami tessellation diagrams.
• TreeMaker: by Robert Lang. Generates crease patterns.
