Mobile audio/video presents & 2-way sms integration in Drupal

I briefly spoke about three related projects than I am involved in. All are related to mobile phones.

1. Audio presents at radio documentary Grenzeloos Geluid

I worked with Nathalie Faber and Carolien Euser of artist collective cut-n-paste on "Callcentre 211" that ran during radio documentary festival Grenzeloos Geluid. Participants registered their phone number at a desk, and were called 15-20 times during the event. After answering their phone (or dialing their voicemail) they heard poems, narrations, soundscapes, music, etc.

I developed this system mostly using Asterisk, a fabulous open-source voice over IP system.

2. Video art presents during Playmobiel exhibition on art on the mobile phone

Every day of the exhibition (except mondays when the museum is closed),
subscribers get an art video, made especially for the mobile phone, on their handset. Subscribing works by sending a text message. The video's can also be seen in the upperleft corner of the playmobiel website that integrates the mobile site.

Technologies used: Kannel sms gateway, php, mysql, drupal, 3gp.

3. Drupal 2-way SMS module

A module to send sms text messages to a group of drupal users.
But the text message is also used for querying the site: for example, by sending "events" via sms to the site, you will receive a message with a list of the first upcoming events.
