I found that the e-ink display on my Aranet4 is, by itself, so distracting on screen updates that I had to move it out of my field of view. It's a full-screen flash. Before buying it, I thought e-ink was a good choice for these types of devices, but now I wish they had gone with a cheap segmented LCD. I wonder if you could actually use this to your advantage here, since you want it to be distracting, and you are in control of the refresh.
