Some illusions are subtle, but this one is quite striking. Very impressive!

Nice work on the GUI. Deserving of nothing less than a 10, IMHO. :tup:
Thanks Xray.
How did you do that with widget? I know that you can Ctrl+c and ctrl+v into notepad for most things but how did you figure out how to use widgets?
Trippy! :tup:
Opened a blank scene. Made a box. Opened color widget for box. Saved scene as test.phn. Opened test.phn with Notepad++ (WordPad also works). Copied widget code. Pasted code into box onClick event.
Thanks for the comments and ratings guys.
One more necessary step which s_noonan did not include above while explaining how to copy/paste a widget is the following: After pasting the widget into the onClick event, you will see in the list of events and variables in the widget code the label "entityIDs". In the data input box for that label you will see a number. You need to change that number to the word: entityID. That way, the widget will get the current entity ID number of the geometry, which will change each time the scene gets loaded.

Thanks Xray. I was working from memory, which doesn't always work out.
Pretty impressive illusion. When you don't look at it directly, the effect gets even stronger.
No problem, s_noonan. Glad to help out.

By the way, I noticed that "pos" in the widget works quite differently than the regular pos in geoms. It seems to act like a position within the display regardless of the zoom or pan settings. It ensures that the widget is always displayed no matter where the parent geometry is located in the Algodoo world coordinate system. That's all I figured out so far, but do you have more to add concerning widgets and how they function?
