32 MOSFET board for high currents

Finally got some loads wired up and had my college age son write some code - so here's 1/ 4 of the board doing its thing! Four 74HC595's daisy chained to drive 32 AOI518, very low Rds, logic level N-channel MOSFETs. Parts selected & power traces designed for an amp per channel. http://www.crossroadsfencing.com/BobuinoRev17/ Short clip of it working with OE set to 1/255: http://www.crossroadsfencing.com/BobuinoRev17/MVI_2864.AVI And my son's fade up & down code while moving around the channels http://youtu.be/hAVf1D1L-7c Kits available for $38, plus shipping (US: $5.35) and 4% paypal fee.
