distort & twist for Mac

From cf/x:

Distort & Twist is an iMovie plug-in that allows you to 'stretch' the four corners of the clip any which way you like. Using a wildly intuitive user interface, you can shrink, fold, twist and flip the clip as you see fit. And since we know what we are doing we have added two important capabilities to the clip: you can either specify a background color for any part of the clip that is no longer obscured by the distorted clip - or you can choose a background picture for the same purpose. The latter feature enables you to insert the clip into any picture (e.g. one of a TV screen, mock-3d perspective etc.)

What should I use it for? Use this plug-in whenever

• you want to change the clips proportions (e.g. after rotating it - but remember that there is a free plug available from us that does the same)
• you need to insert the clip into a still picture (e.g. map with pseudo 3-D 'window' for the actor/clip)
• you need slanted picture-in-picture (narrator/map) documentation
• otherwise want to distort the clip
