Solidify is a modifer plugin that takes your surfaces and makes them solid. An easier way to describe it would be to say that it does extrusion along vertex normals.
Push inflates or deflates an object along its vertex normals. It can be animated too. Possible applications:
Making clothing out of body mesh
Having an object appear to breathe
Making a hand beefier or nose smaller
Bitmap Collector will scan your scene for the bitmaps you use and either copy or move them to the destination directory that you specify.
Stamper Allows you to stamp your embossed image into every frame of the animation ala TV station ID's
Area calculates the surface area of an object you pick. Source code included.
