Personally I think that design ideas 1, 4, 6 and 10 the beast. My favourite one is definitely number 6, ill put them in order of preference
6- I like this one so much because its so quirky. What better way to store your Alton Towers merchandice than in Alton Towers? I also like the design because of its simplicity- it shouldn't be too hard to make, but looks the part and I would buy it if I saw it on a shelf in TowersStreet. Maybe if you added slots for the Lazer Etched Glass Paperweights it would be better- I have collected both the Thorpe, Alton and Smiler blocks among others. I think that would be an excellent way to showcase them, especially if it had LED lights underneath each hole
4- its a smiler carriage. I mean, come on, that great. The idea is good, it fits the current focus of Alton Towers at the moment, and its very suitable for the target audience you have, which is of course tourists and MAP holders. I think that its quite fitting. Your idea of having the Smiler music is smart- although it is hard to get your hands on. I think the LEDs would be better suited in another design though... you dont want to overcomplicate it, amd of course with all the electronic add-ons you would need batteries for it.
1- Another great idea...again quite simple in its look and the design can fit in pretty much in any room you want it to. I think the concelt is good, and you could even add a strip of lights down the actual track section for that extra wow factor. Maybe it would look more impressive if the track was twisting, if u want I can show u what I mean over PM or something. Simple but effective, and it is very general as everyone who has ridden a rollercoaster and liked it could buy that.
10- I find this one good as its very useable in a range of circumstances, as in it canbe used either for theme park keyrings/memorabilia, or (for example) as a key rack or another thing like this. Sorry this answer is shorter than the others, I need to go soon.
in response to your original questions-
My shelf would be over my wall above my bed, so I can see it whenever I am about to sleep and think of the good times
I would display my collection of Paperweights and my keyrings, and maybe my old MAP as well as my Blivvy hat and my set of pens (they ran out a long time ago)
Id go for LEDs but probably nothing else unless it amused me, and the LEDs would have to be low power so I didnt have to keep changing the batteries
I wouldnt mind about the wall fixture, sorry I dont really have a preference but being a 15 year old boy generally wall fixtures dont really concern me
I do not have any theme park bears, although I know nobody would be suprised with me if I did.
Hope this is helpful and if you need anything else dont hesitate to PM or add another post in here!
