I use a projector to paint buildings with light. If you live near SF, join up with orgs protesting billionaires stealing our future.
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?
@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 :)
Why tag me?
If you look at their username thing, you can see that they're replying from Mastodon, not Lemmy. It's some weirdness Mastodon does that Twitter also does where it tags the person you're replying to and people tagged/replied to earlier in the thread you're replying to by default, unless you delete the tag before you post. Most people don't delete the automatic tags. So they probably didn't do it on purpose and may not have even realized they did.
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, what kind of projector?
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).
Still... software?
Most of them are static images, so... any picture editor?
I love it!
What are the hashtags for? Is that Twitter stuff? The idea is cool, and it's awesome that you're doing something. I do think it would be cooler if you posted your website address. A lot of people don't use Twitter, and it's run by a harmful mega billionaire.
Hashtags work on a wide range of platforms and double as search terms. It probably sticks in the mind of the average passerby better than website and gets people to your message about as well overall.
Yeah. They existed before Twitter too.
What platforms used it before Twitter?
Well, back then I wouldn’t call “blogs” a platform. But that’s what helped popularize tags.
Did blogs share tags? I can't recall, but I believe you. I do remember backlinks.
I don’t think so. At least not as a matter of course.
But they did help organize content, and helped search engines as metadata. At least before (?) SEO destroyed their utility.
Yes, the hashtags are for the poor souls who use other social sites. Here is a link for more info on APEC. https://ilpsusinfo.wordpress.com/no2apec/
Thanks!
i don’t see it
Don't see what?
hashtags
They're in the projection on the side of the building, at the bottom.
the image didn't federate
The hashtags are for people using other platforms to find more info. Here is a link for more on APEC. https://ilpsusinfo.wordpress.com/no2apec/
am see noaw
Is apec Asian Pacific Economic Cooperation? Or is it referring to a different acronym?
Edit: found this https://www.apec2023sf.org/
I'm glad to see some exposure, but I can't help but feel the message is misfocused; lMO Solarpunk is about which actions to take not just saying "yeah me and all my homies hate XZY".
Its much easier to get people to agree on an action, like right to repair, see the benefit, and then draw their own ideological conclusion. Its much more welcoming and positive than than jumping straight to "my conclusion is good, you should hate XYZ with me"
I don’t think it is true that it is easier for people to agree on action compared to uniting against a common oppressor. Something cutting is often more attention grabbing. But it isn’t an either or. We should use both positive and negative messaging to grow the movement.
