Wow, congratulations, that&#x27;s really cool! Speaking of errors, I remember receiving the &quot;Expression was too complex to be solved in reasonable time&quot; error when I was first implementing Catmull-Rom splines for calculating flight paths in a game that I developed. I translated that to, &quot;The math is making the room spin up in here.&quot; Definitely the &quot;coolest&quot; error I&#x27;ve hit working with Swift.
