Light Bender - A laser cut laser game i made

How do you guys deal with the aftermath of a big project?
I don't know about you but i tend to approach things a little less scientific than I'm probably capable of and as a result i end up with all this very cool but useless stuff!
Is it worth keeping it all in a box to one day make in to some kind of mega-thing? or do you chuck it since you can probably make it again?
