One of the things I really enjoy are DIY things and admire ppl, coming with great ideas and making our life more colorful. Here is an example – http://www.imaginarymarchingband.com/.

Those guys are making small prototypes of instruments so you can play you’re favorite marching band instrument only by pantomiming with your hands. I really enjoyed the video with the mom playing on cymbals. She looked so excited :))

And there is an option to back up the project on their kickster page http://www.kickstarter.com/projects/979856363/the-imaginary-marching-band

Enjoy!
