The company Constellation 3D had a technology called ("Fluorscent Multi-Layer
Disks") that promised 1.5 Terrabyte optical discs for a price of $10 each. Their
web site has disappeared, so I assume they've gone belly up. Does anyone have

they were forced into bankruptcy by the fickle nature of the stock market?
