Just saw The Exception on Youtube. Mind-blowingly awesome, one of the best ball machines I have seen! I love all the brand new elements (and there were lots). Then I saw the reference to instructables in the element videos and became even more excited! ;-)

Thanks. Do you think you are going to use some of the elements? :-)

Hey! Nice to see you on instructables. I watch your knex ball machines on youtube a lot. You make some pretty amazing stuff.

Great! I can't believe how you keep inventing such amazing new mechanisms! The Exception is truly amazing :)

oh yes, new and awesome stuff :D

Can you please put videos of these in your 'ibles as well? All these awesome things you are making look truly... awesome, however, a video would be very helpful to find out what exactly it does without having to build it first.

oh yes, new and awesome stuff :D
