a LOT of backgrounds and background masterposts i’ve collected! pixel, nature, tile, + more!! uvu
i feel like this summarises modern art
This is Mercury, the T-rex kitten. He was found at just four days old with horrific injuries. It is believed a weed whacker was responsible for his missing front legs and a number of back toes. His dedicated parents nursed him back to health and now he is a playful 6 month old with some serious leg strength.
Unfortunately, Mercury is not a candidate for prosthetic arms as he needs to have at least 40% of the limb intact. But that doesn’t stop Mercury from having a good old time.
Stay fierce Mercury!
when i was younger i had a really bad fear of vampires when i was going to sleep so my older brother gave me a watch that he set to like 8 hours ahead so that it was always daytime on the watch when i was asleep and he told me it would confuse the vampires and they would think it was daytime and get scared of the sun and leave me alon
Your brother is the best
Running into DC characters, always a good time!

This lamp absorbs 150 times more CO2 than a tree
It’s still in the “so crazy it just might work” stage, but these microalgae-powered lamps, invented by French biochemist Pierre Calleja, could absorb a ton of carbon from the air every year. That’s as much as 150 to 200 trees. [x]
YOU DON’T UNDERSTAND. This is ingenious.
The design is a light bulb surrounded by a glass casing. The glass is filled with (water based) media and microalgae. The top is permeable to gasses so that gas exchange can occur. All of the wiring is linked to the grid underground.
Since the light source is inside, it gets scattered and “dimmed” by the water and algae. This makes it less glaringly bright and scatters the light wider, which is good for a street light. It is not longer white light as well, which helps make it easier on the eyes while still providing light.
At the same time, it provides the light for photosynthesis in the algae, so they are continuously exchanging CO2 for O2, not just in the day. It also provides a source of heat, which helps keep the algae from going dormant during cold weather (as in the snowy picture above).
And notice how I did not specify permeability - that’s because NOx’s (NO and NO2) are also permeable and can be used as nitrogen sources to microalgae. In fact, algae are relatively low maintenance. As autotrophs, they don’t require super complex media, not does it really need to be changed/added to. (I’m actually fairly certain that there would still be algae in these tanks a year later; it may need to be cleaned or something, but there would be some living algae.)
when your friend gets something done that they’ve been wanting too and talked about it all the time and you just feel so good for them you’re just like
