Hello Yogendr, Sir,
Wow, how many creative people can read your post and not have a creative answer for you?
Anyway, here's what I would do. Get some glue that dries soft and rubbery and glue a magnet on the back, then keep it as a souvenir. Then it will stick to any metal surface to keep and make people ask questions. I do this at work with very old technology, like EEPROMs (used for many things, but commonly was used in early computers as the BIOS memory... removable, erasable by UV light, then reprogrammable with a gadget). Old cache memory that was separate from the CPU (early Pentium era, maybe even 486's), laptop memory as big as your fist, etc.
You could plant an "Easter egg" in it, format it and put maybe video or an animated GIF of yourself. Then when someone gets ahold of it, maybe after you retire, if they have the gumption to clean off the glue and plug it in, they get a surprise.
I'm sure you can find something fun to do with it.
Best wishes,
jon
