Here's my problem...too many ideas, not enough action on them! When I find and then Google my great ideas to what other people have done, there's 50 models that are the same idea but 10. times better than incould build i.e. a Cessna 152, train/subway cars, f15 jets, airport terminals.
However, I do have great ways to get inspiration and ideas for making mocs. Eventually I'll create one of the ideas. Here's some good ways to get ideas for mocs...
1) magazines
Any magazine has endless ideas for mocs, usually great pictures on the front cover. Even the lego club magazine has hidden ideas in the art in the backdrops for the main story...
2) Hallmark store ornaments! And Hallmark store...
3) Die cast cars/trains (often at cvs, restaurants with gift shops)
4)Matchbox. Johnny lightning brand cars...Dollar Tree and target. Usually bigger car toys are seen at Walmart and Target
5) isometric art
6) plastic model box paintings
7) my favorite..Toys at thrift stores
No idea what the above 2 pics are...some chassis, but cool greeble effect!I like toys that give a proportional idea of how big the wings, or how much of a chassis is taken up by the cabin vs. Trailer on the truck.
8) General toy aisles at drug stores cracker barrel, tourist sites
Halo and wooden craft vehicles are inspiring i.e. the trains above run on 8 wheels vs. 2 bogies.
