Here’s an app I wrote recently for drummers which allows you to use your iDevice as a single-channel drum module for your kick drum. It has 35 kick drum samples with a range of styles from rock to techno, and you use it with a standard piezo drum trigger in combination with a guitar input such as the iRig2.
Using EZTrigger allows you to augment your bass drum in the mix without having to mic the drum or set up a separate drum brain or module with all the extra cords and whatnot. There’s a separate site for eztrigger (http://eztriggerapp.com/) where I’ll be posting news, updates and support material.

Now that Parse has shut down, and developers are looking for alternatives, here’s a quick proof of concept called Farse I wrote a while back. It’s a service clone, which leverages Objective C’s Key-Value coding and the Apache Software Foundation’s project Solr to model a schema-less, nosql database with rest api and iOS client library. (The Parse service offered quite a bit more than this, such as push messaging and server-side code execution, which Farse doesn’t address)

When I first saw Parse, Solr immediately came to mind as it provides the schema-less database and REST api out of the box. It seemed to me that one could create the client side using the “modern” objective c concept of object subscripting to create fields ‘on-the-fly’ which could be serialized to and from Solr / json.

If you’re interested in building your own Parse service clone, I present this as one way to start.

There’s a github repo with the code which includes a readme and a pdf document tutorial on how to set up solr on your local machine to try it out.

Here is an example app showing how to use the instagram search api to retrieve photos based on user location:

• CercaPix

One of my freelance projects a while back was to make an html version of iCatalog for International Color Services. The web version takes screens from a pdf created in catalog prepress production and linkifies the products in it. For a time this was used on customer websites, and I have archive some examples here:

• Anthropologie
• Avenue

These are several years old, last built to work with iirc, Internet Explorer 5. Beware, the zoom feature is a bit banged up on one side, and the product links are stale, but for the most part it still works!

Update: Just released a newer version of this app which handles the migration of source site glsl.heroku.com to http://glslsandbox.com/

Here is a fork of a project I found on github that retrieves shaders from glslsandbox.com and runs them.

I hacked it a bit to make it run on ipad and  load the gallery. Fun for tinkering with fragment shaders on the iPad. Very alpha but if you are a developer and like glsl, check it out.

An old classic, Explode — written for ios version 1.0.
