Definitely not going to get my other two ideas done (or even started), so you'll have to imagine them for yourselves. Here's a word-render of the first:
First Non-Entry, entitled "...By Redirecting All Sensory Input": A lakeside with five side-by-side jetties (I picture ramshackle wooden ones - I'd have used Ravyn's "Bridge To Willow Deep" from CP) at the (wet) end of jetty 1 is a nose on a pole, jetty 2 has an eye, jetty 3 an ear, jetty 4 a tongue, and jetty 5 a hand. There's a short path connecting the jetties, and this leads a short distance to a huge brain. However, sitting in the middle of this path is a huge ugly monster (Sixus1's "Rancor" probably) holding two road signs: in one hand "Road Closed", in the other "Diversion". The diversion sign points to a far less obvious path from the jetties leading off-picture with a sign saying "Scenic Route".
(I'd probably have used Dusk's nose, eye, ear, tongue and hand in the image, but I'm not sure whether just using parts of him would have met the entry criteria?)
Don't even have time for a word-render of the second (plus it's a bit more complicated) at the moment
