This sculpture was in the works for 3500 years

I just finished a new sculpture, consisting of 70 end pieces from reclaimed redwood boards. Each piece shows about 50 growth rings - and that makes it a total of 3500 years (of course not sequential since most of the trees grew at the same time, but still...). The sculpture itself is a growth curve with ups and downs to illustrate how life or pretty much anything develops over time. Take a look at more pictures of the wall  sculpture.
