Webtube University of Pennsylvania

ZeitPlanner University of Pennsylvania


Definitely check out the full list too because there ARE some great apps which didn't make it into the final 20.


Agreed. Including a coffee pot that emails you when the coffee is made and a toilet that live tweets your music habits.


You guys should check out Mosaic: mosaic.launchrock.com

turn multiple phones into one panoramic view... for anything... including video.


Anyone else think the inventory app has some serious potential?


Yes, brilliant.


yea it's a great use of RFID and i hope to see it commercial within the year


I wrote a similar app to SparkTab, even came up with a similar name. https://github.com/siliconcow/ARC

Haven't touched it in awhile but the one I ended up using was 'stach' which mustachified the first result in a google image search. It's also nice for organizations that can't decide on a groupware solution and you want a quick way to search anything that takes a query string.


Great showing from the University of Michigan! Go Blue!


ZeitPlanner would could be very handy. It doesn't have the same WOW factor as Visual Perspective - but it could be very useful!


You can write a simple cost function and then brute-force all the options in no time. I did that in school.


Wow the Virtual Perspective app is incredibly impressive for a 48 hour hack, especially considering it was done on mobile.


Honestly, that just blew me away.


And here are the winners!

First place: Inventory Second place: virtual perspective Third place: Webtube


How do I get Virtual Perspective on my phone? I see it was an Android app... I'd love to show it off to my iOS friends lol.


The music sequencer was awesome. Go Blue!


The music sequencer was awesome is there a live site I can see it?


[Max from the Team] Unfortunately, we don't have it up on a site. The reason here is that the MIDI keyboard is connected via USB, and thus would require us to establish a TCP connection to the server. The additional latency could definitely have a negative impact on responsiveness, which is a tradeoff that we didn't want to make at this time.

That being said, remote hosting of the site would be the next big feature, if we continue working on the application. ;-) [edit]


Paul from SoundCloud here. Definitely think about shipping a version that uses a web keyboard. The app is too good not to show off to everyone!

Also, got a video of your demo. I'll be posting a blog post on developers.soundcloud.com in the next couple of days. Great work!


Congratulations I think it's awesome and would really be great for people who want to make mashups/mixes but don't want to spend a bunch of money on the equipment. Good luck to you and your team!


You should just put it up with a javascript keyboard! I'd love to play around with it.


I think they're right, please release a version that could be controlled by a keyboard + integrate Youtube's API and you could probably break the Internet because it would be too awesome to handle


Gaurav from the Cloud Sequencer team here. After the awesome response we've been getting, the team is going to work on putting out a public version.

We'll make it compatible with both MIDI controllers as well as your laptop keyboard. We were initially using the YouTube API for samples, but the latency issue was too large and responsiveness of the keys were one of our top priorities (especially when doing something like drumming). Having entire audio clips buffered client-side made for a much happier hackathon. We'll look into how we can better control buffering YouTube audio data so that people can sample from there as well. So YouTube is a maybe for now depending on if we can make playback responsive enough. Regardless, We'll do a ShowHN as soon as people are able to start playing with any form of the sequencer.

What I really want to see is Cloud Sequencer making it really easy for anyone to try their hand at sampling and mixing audio without expensive equipment and software. Unlike other members of the team, I hadn't done much audio work before the hackathon but I'm hooked now. It was a lot of fun. Thanks to PennApps and everyone who stopped by to play some awesome music with us.


Hamilton - big up! Really like drag and drop canvas interfaces...
