This year for my BFN display I am considering music. I am building mine boards using scaffold boards with 11 x L brackets on each to spread across the football pitch in 6 firing sites to start with a sweep of 36 mines firing 0.4 seconds apart. The finale is 30 mines fired simultaneously creating a 40m high wall of Brocade across the field. I have needed to invest in a professional one shot capacitor discharge blasting machine as I will need over 70v to ignite all the e-matches off a single que. It will take practice to get anywhere close to this video!
