Adrian Freed: ipads in motion sampling temporal texture space

May I suggest a small but important shift in the way of thinking of
imaging on the displays. Instead of referencing the image to coordinates
established from the edges of the screen, think of the edges of the
screens as addressing locations in a larger virtual world.
(i.e. "a temporal texture space")
Use the accelerometer to "move the frame" in the larger space. This is
an oldish idea that I have seen revived several times in the last
decades. (e.g., Jaron Lanier described it to me a few years ago and Sun
research did it in a PDA prototype before that). Now the displays that
are hanging like bats in  a cave can be swung from pendulums or blow
around in a breeze (there are some nice energy effficent
rigs for this with muscle wire). This motion is important for me for
two reasons, it can be used to create experiences like
the shimmer of leaves blowing in the wind where the matt and shiny sides
modulate temporally (also fields of wheat) but also it defeats
a problem I have with screens in theatrical contexts which is most
apparent in the "magic mirror" trope when activity in real space in
front of the screen is transformed and reflected back behind the real 
actors/dancers. The problem is that the screen is anchored 
and the action isn't so when you move your head the screen reveals
itself throughout the image instead of framing the image
thus defeating the necessary suspension of disbelief for cohabitation of
the screen information and the action. This is analogous to the sweet
spot and uniform directivity problems in audio that we have been

As for the iPad choice: you might want to wait for the slew of
competitors coming out. HP has one
coming out real soon and a lot of programmers I know prefer other OS
development tools for such things.

Finally, remember if you are willing to live with lower overall lifetime
of the leds (a year or two instead of 4 or 5) you can increase the
backlighting brightness considerably:

Hi Harry, Patrick,

This may be just a digression.

To complement the fine and saturated power of lighting instruments ...
if I buy iPADs for to play with in the lab for Michael,Tim and JS, I would like to invite us 3 to think orthogonally to the usual pathology of screen-based play.

What if we (when we get the budget) get many iPADs and find a way to suspend them in space?    What if we think of them as 

(1) addressable light panels -- expensive light bulbs -- FORGET IMAGE !
(2) windows into other parts of the same room (so we need to get a lot of inexpensive cameras and a video-mixer)

What if we
(A) Float them on aircraft cable from the grid at different heights in the air.  Let's figure out what heights and densities have what effects
Finally we can try to something I've always wanted to play with more.

(B) Introduce rhythms into them by sequencing

(C) Introduce responsive behavior.   a brute force but perhaps effective sketch method: map Jitter into large video matrix, then beam submatrices to iPADs?
