A gift for my grandparents, the hardest one to find. They have everything they possibly need. Ideas anyone?

I know that they'll be happy just receiving a gift from me, but i still want it to be special. Any time my granny (don't laugh about the fact that i call her that) gets a cheap little gift from her friends (like bath and body works, fake flowers in a vase, candy basket) she ends up giving it to me. I don't want to get her one of those gifts that she's just going to want to give away. I also don't want to make her feel guilty into having to display my gift or keep it even if she doesn't like it. I never buy them gifts because I never know what to get them, but this year I really wanted to do something nice for them. They do so much for me.

How about putting together a little segment of their lives on DVD? You can include pictures from when they were young and everything thats led up to now. It's cool to have it mixed with live video if you have any. A friend did this for me recently with video & pictures from our vacation and it was awesome. Oh and add some appropriate music ! That should give it a good feeling of nostalgia. It may sound cheesy to some but if done correctly it's awesome to see visually, It's not your old fashioned slideshow.It gives such a differnt feeling to see glimpses of many events on t.v. all at once. GOOD LUCK :)
