What are some interesting sequences of functions for thinking about types of convergence?

I'm thinking about the basic types of convergence for sequences of functions: convergence in measure, almost uniform convergence, convergence in Lp and point wise almost everywhere convergence. I'm looking for examples of sequences of functions that converge in one or more of these ways, but fail for others. I keep seeing the same examples over and over and I'd like to think about some new ones. Here are the examples I've seen:

$f_n=\chi_{[n, n+1]}$

$f_n=\chi_{A_{n}}$ where $A_1 = [0,1]$, $A_2 = [0,1/2]$, $A_3 = [1/2,1]$, $A_4 = [0,1/4]$, $A_1 = [1/4,1/2]$ etc.

$f_n= n\chi_{[1/n,2/n]}$

These are a great set of examples since they let you give a counterexample for the relations between the types of convergence when needed, but I would like to know of some more.
