I usually stare at them in admiration behind their dimensional windows (glass cabinet doors), contemplating whether or not I should fiddle with them or just leave them be and continue staring at them.
Usually about maybe 5 times a year (or less) they will all get transformed into one mode (you know, to make sure I don't forget how to do it) and eventually back again. Occasionally I might just transform one or two that appeal to me at the time. Usually when they are undergoing their quarterly transformation
I do it while watching tv or talking with the wife. Although I get told off for not listening to her when I do that.
I do sometimes "improve" the figures with minor paint apps and/or reprolabels, but usually only if they REALLY need it because the original is lacking in some way.
If I see a figure that would look great painted up properly I will have a go at a full on custom paint job makeover, but I've only really done that a handful of times. It only happens when I get a creative burst of energy, which doesn't happen often.
