Video Mill

Video Mill is a peculiar app that lets you play different videos simultaneously in different windows of personalized sizes.

The program supports videos in MPEG-4, DivX H.264, Xvid MP4, MPEG-1, MPEG-2 DVD, SVCD, AVI MPEG-4, WMV, Flash, Quicktime M2V, M4V, MOV, Apple 3GPP2, 3GP, VOB, TS, RM, RA, RAM, and many other formats. Of course, you can play several videos at once, regardless of their format.

The program's configuration options, which are many, let you establish different keyboard shortcuts for each window so that you can move them quicker, change their size, and bring them forward or backward in a second.

Video Mill is an interesting app that, even if it isn't particularly useful for most users, can be great for giving presentations.
