TITLE: Lights out game on hexagonal grid
QUESTION [13 upvotes]: I greatly enjoyed the Lights Out game described here (I am sorry I had to link to an older page because some wikidiot keeps deleting most of the page). 
Its mathematical analysis is here (it's just linear algebra)
Now I just discovered a hexagonal version:

  (and hopefully soon) https://sites.google.com/site/beyondlightsout/

Are there any mathematical results for this version of the game, before I dig in and start the analysis myself. I have the major references including  

Turning Lights Out with Linear Algebra, by M. Anderson and T. Feil (1998). Math Magazine, vol. 71, no. 4, October 1998, pp. 300-303.  It's here (thanks to J.M.).

Update: I've been playing with the iPhone T-Lights hexagonal versions. I can get most of them, except for the ones where the "template" is a Y shape. Any ideas?

REPLY [3 votes]: I tried (and tried again) to improve the Wikipedia article but the edits were promptly reverted as if well-known solutions of Lights Out are "original research", despite providing several citations.
If any Stack Exchange members are Wikipedians who can assist in restoring the article, it would be greatly appreciated. Also, I would direct this request more appropriately if I could, but don't see a way to contact John Smith directly. Feel free to delete it.
