From Jon Hyers and Outrageous Media. Giant Spiders, with more than 40 Effects Chapters, was made to be an EXTREMELY usable DVD with a lot of variations on the effects. First, you get Single and Multiple Spiders ranging from Large, Very Big and HUGE. Spiders come in a variety of backgrounds. WHITE background let's you project Spider directly onto Wall or Ground, and the white light around the Spiders illuminates your wall without additional lighting. BLACK backgrounds let you project only the Spiders. Room/Wall/Ground scenes also appear with the Spiders in various forms. For example, many spiders crawl from a hole in a cement wall, all of which project as the image you use onto your white surface [wall, garage door, screen]. But the same effect comes with a white background, letting you project this onto the side of your house or wallpaper, making the spiders come from any of your walls [without the cement texture being applied].
