I would like to find a large catalog of LEGO designs/ideas that can be built with "traditional" LEGO bricks (both normal and DUPLO).
I have found many nice designs in the web, but most of them require exotic pieces. I am interested more in a catalog of models (for inspiration) that do not require me buying a specific set or making a specific order to the LEGO shop.
I found this book: http://www.amazon.com/exec/obidos/ASIN/0756686067/geekdad0b-20 but I am wondering if a free resource exists somewhere ?
UPDATE:
I have just read this review of the book I linked above, apparently, it also suffers from the problem of requiring too many non-standard pieces:
We thought this book would be great since my 5-year-old is just getting into LEGO bricks. Opened it up and realized that every project in this book looks like it requires non-standard, specialty LEGO kit pieces- and lots of them. I didn't see any projects in this book that you could build using standard LEGO pieces. Returned the book the next day.
