Um bando de hackers se reuniu em NY para criar doideiras relacionadas à música. Coisa fina. Abaixo, os três vencedores, começando pelo primeiro.

With a Nintendo Wii controller in his left hand and an iPhone in his right, Tim Soo wowed the crowd with his collection of invisible musical instruments, including a violin played with (of course) an invisible bow, a phantom drumset, and a literal air guitar.

Soo presented the guitar at Music Hack Day Boston, but he has made lots of progress since then — just listen to the gasps from the crowd as he bows the violin, above — so attendees awarded him the top prize anyway. His system takes the physical inputs from the Wii controller and iPhone and applies them to a custom Max/MSP program to create the resulting sounds. Stradivarius himself would have been impressed.

The next time you throw a party, try Dan Aminzade’s dj.txt, which lets people request songs using their cellphones’ SMS or Twitter client, displaying the queue on a computer or computer-connected television for all to see.

The interface is quite slick, and partygoers can request songs by simply texting the artist and song name, which dj.txt understands. But there’s a lot going on underneath the hood of this deceptively simple app:

  • Twilio to send and receive text messages,
  • Grooveshark to play the music,
  • TinySong to look up songs in the Grooveshark catalog,
  • to display album covers,
  • MusiXmatch to display lyrics for the current song,
  • The Echo Nest to display stats about party playlists on the recap page, and
  • Twitter, to receive song requests via tweet in addition to SMS.

In addition to requesting songs, attendees can text the word “skip” to move on to the next song. After the party, djtxt lets you hear every song that played at the party via Grooveshark while displaying their energy levels, hottness and danceability ratings as determined by The Echo Nest

Stringer allows the user or the programmer to paint invisible lines in 3D space that can be plucked like strings. The longer the invisible line, the lower the note — just like with a real string instrument.

We caught an early glimpse of this project, created by Alex Chen (designer, Google Creative Lab, featured in the video above), Aiden Feldman (web developer, LimeBits), and Tyler Williams (developer, The Echo Nest), some of which is based on Chen’s widely-acclaimed work on, which turns a map of the New York subway system into playable strings. This installation adds integration with Microsoft’s Kinect device so that strings can be drawn and plucked by movements in real space.
