I need to give an awesome maid of honor speech at my best friends wedding! Original! Not the traditional kind!?

Do a slideshow of pictures of your best friend and the groom and narrate as the pictures go by.

I think that you have a good idea with using either a movie or slideshow.
If you have the time to do it maybe you could make a videotape for them. You can ask friends, family and bridal party members to say something nice to the bride and groom. Then when you go to give your speech you can say something heartfelt, then follow it by a funny video of all their family and friends wishing them the best.

This may sound crazy but I would check with your friend the bride first. because often times brides envision the moment when their maid of honor says all the traditional wonderful things about your friendship and your happiness for the couple. Additionally you may need to run any media things by her to check with the venue and/ or DJ for sound help. So original is great but just check with her first, not in detail of course you want to surprise her if possible. good luck.

I agree with Amy, run it by the bride first. You dont have to give her exact details, but you should most definitely run your ideas by her before you make any definite plans. Also, your presentation should be no longer than 3 minutes (and thats even too long), making a movie would take much longer.
An idea that I did for my bf’s wedding was, I spoke to both parents and they helped me collect photographs of them over the years. Then I arranged them and made a slide show. We set up a laptop on the gifts/guestbook/seating chart table and guests could see the show as they meandered throughout the evening by the table. Everyone loved it and they could look at it at their liesure. I was also able to have a copy made with music for the 2 of them to have afterwards. Maybe that would be a better alternative for you.

Quite frankly I think all the toasts at weddings are overrated, too long and boring, just make it short and sweet and get on with things.
