Following the Phyllo demonstration video we recently shot, Xavier and I started thinking about the impact of the flash frequency on the Phyllo effects. The first step being to list the effects we want.
There is a variety of effects that depend on the flash frequency; they all boil down to what we’ll call the “apparent rotation speed” of the Phyllo. Here’s a well-rounded selection of effects to give you a better idea of this:
We could define this kind of effect as having an “apparent speed of zero”: the petals only age or de-age along a top-down line, but don’t move left or right spinwise.
Notice that when the petals age or de-age along a straight vertical line, if we light up a whole spiral instead of a single petal, the spiral seems to rotate around the Phyllo.
On top of the aging or de-aging petals, we could also move them all sideways between frames by slightly increasing or decreasing the flash frequency. This could for instance be used to match the movement of the petals to the angle of a spiral, so as to give the impression of a non-rotating spiral:
And of course, from there all manner of spiral speeds, in both directions, are possible by tweaking the flash frequency a bit. Here is an example:
In an upcoming post, we’ll talk about how to actually flash the LEDs to produce all these effects.
Stay tuned 🙂
