Tell us about yourself!
It's not a technique you see often and usually attracts a crowd, I first saw my father do this (including building bridges between towers) in the 1960's in Cornwall, UK. Good to see current practictioners.
My Father has a small quantity of Aston Martinite, he also made a few objects with it in the 60-70 when he worked there. A couple of pieces have flecks of gold paint, so saving those for a special project thanks for jogging our memories about possibilities.
Thanks for the inspiration for the catcher, I had some N52 magnets so I Sugru'd one below my bottle opener. Yours is way neater but you inspired me all the same
