Alex Schlegel‘s Day Table uses a photoresistor located in one corner, and eight ShiftBars (for a total of 24 channels) connected to an Arduino to play back the sunlight that fell on the table during the course of the day.
Recently I’ve been thinking about a LED displays. Originally, I was thinking about a full 640 x 480 display, but after doing the math, that idea quickly shrank to a more manageable 32 x 24 display. While part of me thinks that having one of these tables would be interesting, I can’t help but think that in reality they’d just be ugly and too bright.
I started to think about LED displays because my “coffee table” (It’s actually more an end table.) has a glass top and holes cut out in the back for electrical cables to pass through. What I really want is a multitouch display like either of these two guys are building. However, a multitouch is still pretty hacky and more DIY than I want right now. I like the idea of owning one of these tables, I just don’t want to build it.
