Creative Labs has just introduced its Lava Producer application ($29.95), available online at www.lava.com. You can use Lava Producer in conjunction with Creative Labs's free Lava Player-an interactive video environment with 3-D images that move and morph in sync with an MP3 file-to customize MusicVideo 3-D (MV3) files incorporating your own visual material. For example, you can take pictures with a Creative Labs Video Blaster WebCam and drop them onto the objects in one of Lava Producer's screen templates. All of this can be done in real time. The minimum system requirements are a Pentium II/233 MHz running Windows 95 or 98, 32 MB of RAM, a sound card, and an OpenGL graphics accelerator card . . .
