Kit bashing is a term from my model building days, I didn't do it that much, but the professionals did it often. What it is is taking the parts from several kits and putting them together in a different model.
Many of the Star Wars models were constructed with pieces bashed together from various real life battleship models! =^^=
In this strips case, I re-used many previously drawn elements from earlier strips, and a lot of cut and paste between frames as well =
that sounds tricky, but could certainly be useful for making some creative models. I do remember I went through a modeling thing, but I kept losing the pieces and the spaceship or whatever it was never completed.
hmm, looking back, I wouldn't mind trying it again, if it wasn't missing. I still get a kick out of building Lego models, they don't even require glue or anything. ^^
Heh, for the first ten years of my modelling experience, every kit I built had a lost or broken piece!
One thing I liked about working on the floor: You drop something, and it is already there! =^^=
As far as model building goes nowadays, it seems to be a lost art. When I was little K-Mart carried a great selection of cars, ships and aircraft. From civilian to military, and all skill levels. Heck I even got my first balsa wood and tissue aircraft from that store. Took me three years to build (started it, got frustrated, then returned again) then the cat ate it! Looked like flack damage!
Now the stuff in Wal-mart is pre-painted and has very few pieces. Great for a beginner, but for someone with a little more experience, they leave a lot to be desired. Hobby shops are still around, but those are dying off too. Video games trump craft skills.
