[NTG-context] Request for some sample technical document layouts.

Hello, I am required to typeset a technical book having several chapters with lot of figures, equations etc. I have set this type of document using Komascript-book class earlier. Now I want to try ConTeXt. I am new to ConTeXt. Can I get some sample document layouts suitable for technical books? This will be very helpful for me to learn ConTeXt. Thanks for your help, Anand
