A big hello to all the lego fans out there! I am a student currently working on a project on spiders and I would love to build a mini threadmill using legos and motors. But I am kinda new to building things with legos and was totally lost when i went thru the catalogue at "www.bricklink.com". Are there any kind souls out there who can advise me on how i can build a threadmill and the materials that i need? :):) Cheers, Qi Qi
