Memory Game
http://www.funbrain.com/cgi-bin/fm.cgi
The memory game is a fun, interactive game that you can play with any cards.  You play by memorising where cards are and taking turns to flip over two cards to get a match.  I thought the memory and matching aspects of this game could be interesting to use in my interaction.  I would have to think of a way to add sound into it though.

Sound Waterfall

I got a lot of inspiration from this application I found on Open Processing.  I really liked how they chose a natural thing (a waterfall) and made it into an application using sound and colour the way they did.  It is a really exciting application to interact with.  I want to try and incorporate something from nature in my design of my application.  An aspect of nature I think could be interesting to work with is weather, so below I looked at some photography of weather.

This application is simple but effective.  I really like how it has a sequence and how it continues playing round in a circle while you interact with the circles to change the sound.  I also like it how the visuals are simple but relate to the sound they're making.  I wanted to use this as inspiration for a design that has a continuing sequence where you interact with it to change the sound.  I will make the visuals and sound more complicated though.
