# See-it Generator
The See it sequence is exactly as the name implies, what you see is the next entry in the sequence. For example,
$$
1
11
21
1211
111221
312211
13112221
1113213211
$$
I learned about this sequence from [Genius at Play](https://www.amazon.com/Genius-At-Play-Curious-Horton/dp/1620405938).
This code just generates this sequence.
