I found it interesting how the author claimed that even though an idea has done before, it doesn’t mean you should give up on it. As someone who is new to physical computing, I try to avoid doing ideas that have already been executed because of the lack of originality it presents. But the author presented many creative ways of fulfilling the ideas that have already been done. He provided a creative account of physical computing instruments and discussed the advantages and disadvantages about them, which I found to be extremely useful and beneficial.
