Introduction
Join Alejandro Jaimes, the founder of the ACM Multimedia Interactive Art Program, as he guest edits LEA’s latest through a stealthy discussion of the context and importance in which the art program was created. In this installment, Alejandro carefully selects pearls of multimedia morsels from the 2004-2006 editions of the art program and deliciously strings them out for your pleasure.

In Lucidity, Jodi James and colleagues describe a movement-based interactive dance performance, while working towards their goal of designing a real-time motion analysis engine, staging and communication systems. 

Chi-Min Hsieh and Annie Luciani then propose a series of physics-based models relating to dance verbs, which are useful for computer-assisted choreography and for character animation.

Jürgen Scheible's MobiLenin and Manhattan Story Mashup are two colorful projects where multimodal user interfaces were built from personal mobile phones, a large public display, the web and multimedia data to allow people to create and share an interactive artistic experience.

Atau Tanaka's piece explores social music systems and malleable music using mobile devices. 

Kazuhiro Jo and colleagues' sine wave orchestra article is a symphony of the concepts and technical details of a project in which sine waves generated by individuals are used to create a collective sound representation.

Then embark on a journey into the workings of evolvable hardware in artistic installations with Raquel Paricio and J. Manuel Moreno Aróstegui where the user interaction drives the evolution of the artwork.

To conclude, Andrew Webb and his team describe a new type of affordance, the choreographic button, which integrates choreography, gesture recognition and visual feedback. 

Author Biography
Natra’s quest in life is to take insightful snapshots of thoughts in an ever-changing world. She is seldom seen without a notebook and pen, furiously documenting her impressions of the things around her.

After a brief but meaningful career as a media and cultural affairs officer in a particular embassy, and a stint as a media manager in a skincare company, Natra decided to delve into the world of freelancing and has spent the last two years diving into various writing projects.

This versatile communications-trained professional has contributed to various publications such as Asian Geographic, WE (World Environment), LightBox and Today’s Manager. She also continues to dabble in the skincare industry as a freelance copywriter.

Her current role as director of media and communications at Julian W. Photography affords her the luxury of exploring Asia’s natural wonders with her photography partner. Theirs is a symbiotic relationship where he takes the photographs and she does the writing.

To accommodate a love for nature that runs deep, Natra also engages herself in many of the Singapore Zoo’s educational programs. As a part-time facilitator, Natra works with school children, imparting conservation messages through hands-on activities. She also writes regularly for the zoo and was a contributing writer of The Field Guide to Singapore Zoo.

Additionally, she volunteers her time as a Singapore Zoo docent and is a consultant to the Malaysian Elephant Appeal, a non-profit organization that raises funds for an elephant sanctuary in Pahang, Malaysia.

Natra is working on her first book: A collection of anecdotes about the late Sri Utama, the first captive-born elephant in Singapore. She joined the LEA team as its editor in February 2005, and has recently been promoted to managing editor.
