Here is an excellent photograph of a crazy lace agate taken by Tom Shearer. It not only shows some really awsome and busy fortifications (banding). It also is an example of 2 separate geological events: starting from the top is typical straight - ish banding, then it starts to exhibit semi - erratic direction change, then the fortifications go crazy (hence the name), after this crazy lace always finishes with a layer of quartz. The 2nd geo event starts below the quartz layer all over again
