ORIGAMI.1

01 / Make something. Follow the real crease sequence for a Dart or a wider Glider. Next Fold animates one fold; use the Crease slider to work it by hand. Undo goes back one operation.

02 / Your own origami. Free Fold lets you draw a crease across the sheet. The right side of your drawn line folds over the crease. Reverse Side changes which half moves. Stack up to twelve folds, undo, or start again.

03 / Throw it. Finish the aircraft, adjust its wings and launch angle, then drag upward on the paper to throw. The Throw button does the same. You can launch up to four aircraft and make a small airborne orchestra.

04 / Play the flight. Drag left or right in the sky to bank the selected aircraft; drag upward to pull up. Arrow keys steer too. Speed shapes brightness and air noise, altitude bends pitch, banking moves the sound in stereo. Atmosphere opens the sky and its reverberation. Loop Flight repeats each landing.

This is a playful, simplified flight model and a guided folding study, rather than an engineering simulator. All sound is made locally. No microphone or upload.
