Cool :-)

One small tiny improvement: Put surface_cache (line no 37) into the function.

I wasn't sure what you meant, so I tried it out. I thought only lists worked like that, not dicts. Neat :)

>>> def cached(key, cache={}):
...   if key in cache:
...     return cache[key]
...   print("cache miss!")
...   cache[key] = "spam"
...   return cache[key]
...
>>> cached("eggs")
cache miss!
'spam'
>>> cached(42)
cache miss!
'spam'
>>> cached("eggs")
'spam'

Either way, I'm not sure it's needed. It just felt a little wasteful to have 1000 copies of the exact same thing in memory, so blitting one copy in multiple places felt better lol
