Nowadays, that a webcam application allows applying special effects to the image from one of these devices is not news, but it is news when you can enjoy it for free.
ManyCam allows you to apply various special effects to the webcam image. The most spectacular, one capable of replacing the background of the screen with an animation or a static image, as you can see in some television programs. But the thing is not there, since you can dress up with masks, put on a hat, hide behind eyebrows or false eyes, replace your hair with a wig, and so on.
Other effects that you can also apply are: add drawings and figures, add a marquee with text, show the current date and time, and much more. Finally, it should be noted that ManyCam allows you to use the webcam with more than one program at the same time.
