This was further brought home to me a few days ago when I discovered the remarkable work of Willard Wigan, born in Birmingham, England in 1957. He creates tiny sculptures measuring a few thousands of an inch. The following quote is from his website:
“His work is ground-breaking - partly because of the astounding beauty of vision which challenges the belief system of the mind and partly because it demonstrates that if one person can create the impossible, we all have the potential to transcend our own limiting beliefs about what we are capable of.”
More of Willard's micro sculptures can be seen here.
