In Chapter 1 of Spidersilk, the novel, Mark explains to Tink about the repeating patterns in the video game world. Of course, he also implies there are repeating patterns within the world too. For instance, Mark uses services that we do, such as Paypal, Starbucks, movie theaters, espresso, car brands and so on, even though he is from another dimension! Not to mention, his daily life is very similar to a pattern too. He has his espresso and falls asleep and awakens while looking at his ceiling each day. From music to Mother Nature, we can find repeating patterns everywhere. Which patterns did you find in the book?
