Theming Into Series...

One of the things I have found happening a lot to me is that my ideas tend lately to 'spontaneously combust' into a host of related renderings of a series...   the latest, for instance, was originally just an interesting idea spawned from someone else's notion of doing water drops on twigs and leaves - and thought of a dripping water faucet reflecting the landscape [sort of an odd way of doing a landscape within a still life]...  and this "Clear In The Air" has sprouted not only the just completed "Breezing Into Blooms" but another in the works, "Leaking Blossoms", a waterfall of drops showing a tulip garden - and yet another of a faucet with an Iris blooming in front of it, this time the faucet being attached to the house, theme/titled "Consequence"...   I often wonder, tho, how much this happens to other artists, as opposed to a deliberateness in planning a series...   there is, to be sure, no complains on this, as it is indeed a manifestation of intense creativity, but for those who seem to have something I never had - a 'block' - I do wonder why such is not found more, this visualization of variations, each intriguing and adding interest to further investigation...
