Resonata Wave Machine an Interactive Physics Toy

Resonata is an educational online physics toy. The interactive Java applet generates geometric animations  representing a spring system, designed to demonstrate many of the universal features of waves.
A series of weights are linked together, so that each is pulled towards its nearest neighbours. This allows waves of motion to travel along the chain. A driving force is applied to one weight, which produces such a wave. Clicking in the display area pulls the nearest weight towards the cursor. When you release the cursor, it twangs back. 
Resonata is designed by Fergus Ray Murray who has many more animations and interactive toys available at his website.
 
 
Here’s my growing list of Interactive Sound Sites which are both fun and educational to play with.

  1. Cheers! I like your list of interactive sounds sites a lot – I reckon that’ll be really helpful with future developments of Resonata (building in sound input and output is a top priority at the moment…) – f.

  2. Jes, here are some ways of approaching the problem of finding links to music files you can play on your web site.1) Copyright. Make sure you have permission to distribute the music/audio file.If it’s your own music that’s ok, if it belongs to someone else you need to have their permission. Almost all commercially available music will be protected by copyright laws which means unless you have a legal agreement to use the work you may be breaking the law by using it on your web site.To avoid this problem look for music that clearly states the terms of copyright use.Many net-labels and artists are using Creative Commons licenses to share their work and encourage others to do so. CC licenses are a flexible way for content owners to declare in advance how other people may use their work.This type of music release will carry a distinctive CC logo and link to an easily read statement outlining the terms of re-use. Using this type of content correctly means the music is safe for you and your listeners to enjoy. You can learn more about this at the following link:http://www.edu-cyberpg.com/Internet/copyleft.htmlTo help people find Creative Commons music I’ve posted a list of Podsafe Music Resources. Podsafe means music that can be used legally in podcast productions and freely distributed online for downloading. You can find all types of ‘free’ music and related info at:http://spaces.msn.com/members/soundblog/Blog/cns!1pXOS7l93k8mqeQ7FlEEmOSQ!907.entryNow that you know a way of finding free music sources the next problem is getting it onto your site.2) Hosting and Bandwidth costs. In this context:Hosting = The act of storing files on a common server and making them available to their owner or others.Bandwidth = The amount of information that can be transmitted over communications lines at one time.Media files like audio and video are relatively large and use lots of storage space on the web server. Importantly these types of files also require plenty of bandwidth to transmit. The higher the bandwidth, the faster the music file loads.Storage space is easily affordable these days but bandwidth is limited and expensive. In simple terms every time a song is downloaded someone is paying for the bandwidth.Once you find a legal and safe audio file to use you need to ask yourself; can the owner/host of the file afford to give me free use of their bandwidth and for how long or how much ? (in terms of time the file remains available for and how much bandwidth will be used over a period of time for downloading)Usually in the case of ‘hot-linking’ to any file the answer is no. It’s simply not feasible to have anyone and everyone linking to the same file on a computer somewhere without there being some kind of resource costs. Any attempt to do so only results in frustration when the URL becomes unobtainable (exceeds the bandwidth limitations).You may need to think in terms of downloading the music file first, then uploading it to storage space provided by a web host, and then linking to the file via the Power Toy (all of the bandwidth limitations then apply to you).Here’s a list of audio hosting services addressing the problem of free audio file hosting: http://spaces.msn.com/members/soundblog/Blog/cns!1pXOS7l93k8mqeQ7FlEEmOSQ!559.entryIn the current climate of podcasting and RSS file distribution more content providers are recognizing the market need and potential for broad bandwidth technologies, including streaming media and the demand for frequent downloading of large media files.Podcasting services are more geared to providing the necessary bandwidth for downloading MP3 files.In practice it means locating RSS 2.00 feeds, in the form of CC podcasts, that provide links to MP3 files (URLs) that can be downloaded by the Power Toy. Not all services will allow this for the above reasons and you need to weigh the situation up accordingly. However, most people involved in ‘grassroots’ media distribution are very happy to see their work and services proliferate.There are many websites already streaming other peoples podcasts such as:http://www.search4rss.com/jukebox.phphttp://www.blugg.com/caster/ Effectively by linking to the MP3 file of a podcast show using the Power Toy you are doing the same thing.Make sure your intentions are clear and always leave a way for content creators to contact you if in the advent they require you to remove the files from your site. To summarize, Jes, always make sure you have a legal right to distribute the music and be aware of the bandwidth issues. If you have any nagging doubts try contacting the people concerned and ask for permission. Most people will be happy to help and glad you’re taking an interest in their work. This is an important area of media distribution that needs to be discussed openly (bandwidth usage). It’s a common question both in terms of audio and video that many users are asking; Where are the links to free content and is it ok to link directly?Side note: Google has 1,930,000,000 references to pages with the words copyright use.
