Cool!
I haven't used an actual 555 in a long time; nowadays, in the interest of reduced component count and board space, I end up sending a cheap little MCU to do a 555's job (well, a 555 or maybe a 556 plus passives plus a couple of gates).
Downside of the MCU: with a real analog timer and discrete gates, I'd never have to wonder where-the-heck that stray trailing pulse is coming from. Or, worst case, I could probe the workings with a scope and see what was happening.
