Thanks! This was absolutely the inspiration - and I've also mentioned it on the page (right under the video) and in the repository's Readme.

Heh I was just about to say, people were doing stuff like this at Parsons/ITP a decade and a half ago, at least...haven't thought about GRL in a while, thanks for the flashback

i’m so happy this is the top comment. i’m someone who found the GRL as… a middle schooler and boy was it the coolest thing i’ve ever seen at the time

This is even older (I think), similar idea of building interactive experiences using off-the-shelf lasers: https://web.archive.org/web/20040202205307/http://www.monzy....

If you want something a bit more "permament" there's the LaserPecker portal 10W engraver.

I was there the night GRL got a rig working, f&m piling gear onto the bicycle cart, and trundling it around Vienna, looking for apt spots to beam things. It appealed to my seedbombing instincts immensely, of course, and is such an obvious idea all things considered.

Apropos civic protest and public art throwing, there is nothing greater than being able to draw rude things on the faces of buildings, or indeed - massive art. It is an immensely rewarding experience - the edifice becomes the canvas.

They moved on to bigger things, alas f passed away too fast, and I always wondered why we don't see more GRL out there, in the streets.

Another great 'public putting art in places' activity, incidentally born around the same scene (metalab), is the artificial museum:

.. a public collection of augmented reality models deposited in strategic locations. I've got one in there somewhere ...

This is what I immediately thought of as well, I'm just grateful you remembered the name of the project.

An absolute blast from the past, thank you for unlocking the memories of me reading these cool projects way back when!

The video is referenced in the article as an inspiration.

kids don't think we have memories.
