I found this one while perusing Pixiv:

My japanese is incredibly shakey, and running the description through google translate didn't help matters much, but the rough outline is a guy puts on a pair of glasses that turns you into the last person who wore them.
On a related note, I have a couple of twinning commissions being done, one by Kyo and another by GooseyPennington. I'll post them once they're up on the respective artists' pages.
