The author has created a text editor which uses immutable data structures s.t. he can do fast undo / redo [1]

I saw a demonstration where he copy pasted a file into itself until it was larger than whatever memory he had in the computer. He could still efficiently edit it (the data pointers were duplicated, not the data).

Pretty impressive.
