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.

• ORIPA: by Jun Mitani. Generates crease patterns.

• TreeMaker: by Robert Lang. Generates crease patterns.
  

• Rigid Origami Simulator by Tomohiro Tachi. Simulates kinematics of rigid origami from .opx or .dxf crease pattern. See samples here and here.

• TESS: by Eric Gjerdi and Alex Bateman. Generates origami tessellation diagrams.

• Interactive Tessellation Display 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.

• 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.
