How I represented the proof of the cellular boundary formula. (Specifically the proof found in Hatcher's book)
First picture for representing the construction of a spectral sequence from a filtered complex.
Second picture for spectral sequences, demonstrating the technique for recording the long exact sequences used in the proof of a lemma in Mosher and Tangora's Cohomology Operations and Applications in Homotopy Theory. Unless you've read the book it probably won't make much sense.
