Two Proposals

Finalized idea's need to be ready for mondays presentation. So i've rounded up two that I believe will be strong enough and original enough to make it through.

Motion Wave

"Using visual motion detected by a camera, you'll be able to push a sound file around and destort the music."

This will have a visual sound wave projected onto a screen with a motion camera. The camera will pick up either the most dense object in view (the user) or by heat, using infra red to detect hand movements and so fourth. Using this input the user can push the soundwave around on screen, in real time. So either pushing parts of the "wave" up or down to create a unique sound.

A sound track will be played for 10 seconds before the user has control, then he/she will need to copy the original track as close as possible. If that user becomes more than 80% accurate to the original track, they win a goldfish.

This will attract the public by interesting visuals onscreen and children wanting a goldfish. Also with the possibility of a ranking system (who gets the most accurate) it provides replayability for the competitive type. But all this will require 20p if the user wants a shot at the prizes on show.

Clapclap

"Visual sound wave which you'll need to replicate with clapping. Accurate clapping required."

Once again, a visual sound wave will be projected onto a screen but in the shape of a circle. This will be constantly pulsing untill the user interacts with it. This time, after the 20p has been received a pre made beat will play from the previous user. The current user needs to copy this by clapping. A microphone will pick up higher pitched noises loud enough, such as clapping to pulse the sound wave.

This pulsing circle will be very vibrate and obviously to wandering public to attract attention. Goldfish, cakes or other toys for prizes will attract the younger audience to participate.
