Repper Frenzy - my favourites

~ alex @ 14:34 Europe/Amsterdam

The past couple of days have been quite hectic here @ studio:ludens. After we put the word out that we had a new tool for you to play with, Repper, it got twittered, tweeted, twotted, twadoozled and twambled. At the moment, we have almost 3500 pattern designs. What we are working on now is a way to make all these patterns available to the community with a nice web-based interface.

We will keep you updated on our progress with that (follow us on twitter: @studioludens), but in the meantime I want to show you some of my favourite patterns.

These are just some of the patterns that have been made using Repper. We are excited about the overall quality of the patterns and we want the best pattern makers to get credit for their work. So, if you recognize one of the patterns as one you made, comment on this blog post and we’ll give you credit!

More patterns after the jump…

Fablab workshop March 27th

~ studio:ludens @ 11:31 Europe/Amsterdam

Last Friday we held a workshop at Little Mountain for design students and professionals in Eindhoven. Our goal was to explore the possibilities of the Fablab concept for designers. Results for this day included three (mostly) working prototypes and a lot of inspiration on what a Fablab should be, Eindhoven Style. Read on for an account of the day, with lots of pictures.

User-centered Innovation

~ studio:ludens @ 17:16 Europe/Amsterdam

I found this amazingly interesting video from Eric von Hippel where he talks about user-centered innovation. For us, stimulating this type of innovation and giving more people access to tools with which they can innovate is an important goal.

What I noted in the examples von Hippel mentioned in his talk was the skill of users to modify a product or create a totally new one. What if users who do not have the tools now to build something will have them in the future. Could that mean that we can access a whole new field of knowledge that has never been used before?

3D Voice Experiment

~ studio:ludens @ 15:29 Europe/Amsterdam

We are experimenting with a 3D shape generator that responds to your voice. Here is a quick and dirty test we did. We are using vvvv to prototype this.
