You could try going old school and using something like a slide, overhead or film projector for static images (with a modern mercury/LED lamp): you’ll get 3x higher light efficiency than colorwheel DLP (color filters lose ⅔ light each) and 2x higher than 3LCD (prisms divide light efficiently but polarization loses ½ of it).
@AEMarling@ChaoticNeutralCzech The two in your projection are definitely appropriate, and are how I found your post. Maybe #GuerillaActivism and #ClimateCrisis. Be sure to use PascalCase for hashtags so that screen readers break them into sane words, and use alt text for your images :)
Cool beans! What kind of software do you like to use to cue up the images?
Most of the projections are not geometry-critical so I think it’s just about projector placement and adjustment.
What’s more interesting: what projector is it and how is it powered? It’s crazy bright for a portable setup.
Also, did you write this?
Please post more photos on the Fediverse rather than Twitter or Instagram.
Powering it is the hard part. I use a lithium battery in constant danger of melting.
Yes, I did write that. More to the point, I wrote a solarpunk mystery novel, which I’ll post about on Monday.
Given the great response, I will post more relevant projections here. What community tag should I use?
Still, what kind of projector?

Why tag me?
It’s how it works when you reply to a Lemmy comment from Mastodon. It will automatically tag the comment you are replying to and it’s parent.
Still… software?
Most of them are static images, so… any picture editor?
