Frothing Milk By Hand
I've used a french press with good success when a steam wand was not available.  Pour some warm milk in and froth away.  You're not going to get the same shimmery-silky texture that a steam wand will do, but it'll be pretty decent.

The combination of a wide surface area and lots of small holes is excellent for introducing lots of air into the milk and keeping the bubbles really fine.
