The Solar and Heliospheric Observatory (SOHO) satellite keeps 12 instruments, including cameras trained on the sun. You can log onto the website [link] and look at some incredible images or, even better, movies of the sun's surface.
I propose having a spherical light fitting in the center of a
room at home which is wirelessly connected to your home's wi-fi connection. Inside the fitting is a projector which displays live images of the sun's surface beamed direct from SOHO.
For a nominal monthly fee to NASA you could keep an eye on the spaceweather and watch swirling vortexes/vortices, spectacular ribbons of fire produced by solar eruptions, count sunspots and so on. Oh yeah - and it produces light for the room too.

Tangentially related idea [hippo, Sep 05 2011]
||I like your linked idea too [hippo]. We should come up with
nightlight based upon a live image of the phases of the
moon and we'll
have the box set.
