I've been a bit short of time for this, otherwise I would have had this out a week ago and started a second entry.
After looking at the 2 entries which have been submitted before this one, I see I'm up against some stiff competition, but here is my attempt, and I hope it raises a few smiles.
I apologise for not making it in the classical demo style - I wasn't sure how it would work, but after seeing to examples and working on this, I think a second entry may cover this.
Now that the excuses are out of the way, I would like to introduce my entry, "Snap 'n' Filter", which allows you to take a picture from your webcam, or load an image from your hard disk, and play with it.
The effects can be stacked, for example, I used the "Live Mirror 1" and "Distort" buttons on the sample image, but there are some proper filters included too - please experiment with the program, and tell me what you think.
The program cannot save the images you edit with it, but if you have even basic image editing software, it should be possible to take a screen-shot of the program and cut and paste the output image from that.
I look forward to seeing more "proper" entries, and I hope you enjoy this one almost as much.
