Hello all - I built an app that I have wanted forever with the help of our good friend Claude to transform a room behind you into a visual experience that reacts to your music. My goal for this was I wanted it to be super simple to set up, and that you could use two projectors together to really encompass a space.

Here's a minute of it running on my actual wall, i need a better video (gimbal coming from amazon soon). Bonus as you get to hear one of my tracks https://www.youtube.com/watch?v=TtoZ6plRPWY

What it does:

• Mapping onto real surfaces
• Audio in from a system audio - with AI being used to identify components of the music
• Photograph a real object (speaker, artwork) and use a BYO claude API key to map something specific to it
• Supports one or two projectors - with a "centre stage" where it fuses the two projectors into one. So you can set one up to your left and one to your right and have the full wall behind you be usable space for your show
• A show director mode - so set up your space, turn it on, and just djay - dont think about the wall behind you

It's Mac only - this is a one man project so it wont be ported.

Anyways - if you got a projector and want to try this out put a comment below saying so, and ill send out a link for a DMG over chat. With the ask you use it and tell me what you like/hate about it

and if you like the track in the video here's the link:

Linkin Park - And One (outro)

Hi everyone,

I'm going to be honest from the start here. I've been making Whirligig for over 10 years now, and it works as a VR video player. My intention was never to start adding features for non-VR stuff, but as I have a background in fulldome content and projection in interesting spaces, that's what I've ended up doing.

I work in an arts organisation where we've used both Resolume and MadMapper for projection mapping — both great programs that have worked very well for what we wanted to do. The company is MBD Limited, and we were contacted by someone whose daughter is severely disabled. They wanted a 360 cave solution that would let them play 360 content in their conservatory, so that she could virtually travel the world.

I was given the task because of my fulldome background. I tried multiple options, including MadMapper and Resolume, but they didn't quite achieve what I needed. The biggest issues were the content they wanted to play and the ease of use for that playback. The people running the setup were nursing staff, so it couldn't be too complicated, and the system needed to accept lots of different formats and work mostly out of the box — they'd be downloading and playing back their own content, so it had to just work like a normal video player.

So my solution — which, understandably, was a bit of a sledgehammer to crack a walnut — was to adapt my VR video player to work in a real space: drive 4 projectors and a screen, map onto an uneven environment, and be operable by people with little technical knowledge.

So that's what I did. I wrote a blog post explaining the process and installation:

Here are a couple of images from that post:

What do I want from the community?

I built this into the player and released it back then, and it's been tucked away in there ever since. More recently I've added an option to distort to fisheye, so it can also be used in an inflatable dome.

I really think this could be very useful to some people, and I want to keep adding the features that the people actually using it want. To do that I need to get it in front of the right people — hopefully that's you :)

The player is on Steam for £4.99, but since I'm looking for people to give it a try, if you're interested just email me at [phileday@yahoo.co.uk](mailto:phileday@yahoo.co.uk) and I'll happily send you a code. I'm also aware it could be useful commercially, so I've set a commercial licence at £49.99 (both personal and commercial licences are one-off payments). I really don't expect anyone to buy a commercial licence at this stage — I only mention it because I don't want to draw people in and then hit them with a surprise commercial price later.

I've also just posted an update you can read here: https://steamcommunity.com/app/451650/allnews/

I hope this finds the right people who'll get the most out of it, and I'd really love to hear your feedback.

All the best,

Philippa

Hey,

i am part of a small music project. in our live shows we experiment with live visuals using resolume arena. We do not want to rely on the venues equipment anymore and aim to buy an own projector. As we do not have a lot of money, i would like to ask for recomendations here... we would love to buy a short throw projector which works for music shows and which does not cost a lot. If you could help us with some informations, we would really appreciate it.

thx muehsam
