Shuffled Camera Feed Puzzle
|
||
|
|
===========================
|
||
|
|
|
||
|
|
This demonstrates using Scatter widgets with a live camera.
|
||
|
|
You should see a shuffled grid of rectangles that make up the
|
||
|
|
camera feed. You can drag the squares around to see the
|
||
|
|
unscrambled camera feed or double click to scramble the grid
|
||
|
|
again.
