I've had the Pixelstick for a long time, and although I've used it regularly to demonstrate light painting at camera clubs, I can't say I've used it to it's maximum for me.
These last two weeks (since I did a talk in Sheffield) I've been getting to grips with the more interesting aspects of its use. For example, you can create GIF's and although you can't host them here on Zen, you can upload them to a site called "Giphy" and access a link from there.
I spent a lot of time working out how to get maximum smoothness from movement, and last night - in a moment of realisation - It dawned on me that you needed more frames for more smoothness. The explanation from the Pixelstick website is not clear - but I think I need constant light (rather than a darkening sky) and far more frames than I have been using.
The GIF below is only made up of 7 frames.... I shall be exploring this further, and seeing what can be done with this technology.
