Light and Seeing


After a long talk with Gerbrand and Daniel we've narrowed down our focus a bit. For my part we went on to talk about light after I showed them some examples of Petros Vrellis' work. His work is what inspired me to work on the bridge and do some programming for the project.

His most famous work is a beautiful animated Van Gogh painting where the animation also creates a soft twinkling melody on its own. Since then he has adapted his work to go on the iPad due to popular demand, which is shown below (Vrellis, 2012).




Another work of his is what got us to talk about light.




Here the light of the candle gives off a nice digital warm glow and a fine mist of digital particles (Vrellis, 2009). But it looks real and it feels very serene, almost magical. I think the main thing that made it feel that way is because the candle is obviously real. The combination of real and digital is what makes it an enchanting experience. The idea that you can merge something that's happening in the real world with a response made in the digital world. I may not have physically been there to experience it, but the fact that it has stuck in my head for so long is proof enough.

That appears to be very relevant to what we're doing. Since our question is about the relationship between physical interaction and the virtual world within the animation.

You can't talk about light without also talking about seeing. Light is the key thing that stimulates our sense of vision. Everything we see is a result of light bouncing back off of objects then being processed by the eye and brain, giving us a sense of vision.

So we've got light and sight. What do they mean? In art it has represented truth, knowledge, and divinity. Goodness is attributed to the presence of light. With knowledge it reminds me of the Greek myth where Prometheus gives humanity fire, which also educates them. The fire gives life.

In nature you get bioluminescence from plants such as glowing mushrooms and various deep sea creatures. Move on to sunlight and it's interesting to note that various creatures, including us, wouldn't have become the species we are today without gene mutations caused by solar radiation in the early stages of evolution (Hessen, 2008).

On to seeing. A blur looks like a blur because your brain fills in the gaps in between since you can't handle that much information flicking past at once. In certain situations if there's a gap in your field of vision your brain would fill that bit in too (Vanderbilt University, 2007). The question here I'm interested in is this: Is it real if you saw something that isn't actually there? If you saw something that doesn't actually see then DID you see it?
