    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 :)
