Generated by taking this seven-letter word list and running the following Ruby script:

words = DATA.read.scan(/\S+/)
left  = "[qwertasdfgzxcvb]"
right = "[^qwertasdfgzxcvb]"
alternating = Regexp.new "^(?:#{left}#{right}){3}#{left}$|^(?:#{right}#{left}){3}#{right}$"
puts words.grep(alternating)

…and then hand-highlighting some of the more common words.
