Captchas taken to the next level in Korea. I had to screenshot and zoom to see anything.
A screenshot of a Naver login page with a green and white color scheme. At the top, the time "08:19" and mobile signal indicators are visible. The main content is centered on the screen within a white rectangular box with rounded corners. Inside this box, there's a smaller, framed image of three pieces of paper that resemble receipts, each with handwritten items and numbers. Below this image, text reads: "This receipt is made virtually. Not a real receipt." A prominent question in green text asks: "What is the total amount of the receipt?" Below this, there's an input field labeled "Please enter t" next to two icons: a refresh symbol and a speaker symbol. At the bottom of the white box, there's a large green button with the text "Sign in". Below the main white box, there are links for "Forgot your Password or ID?" and "Sign up". The very bottom of the screenshot shows navigation icons: a left arrow, a right arrow, a refresh symbol, and an "x" (close) icon.

#Jfokus went the extra mile and ordered snow.
A street in Stockholm with a little bit of snow on all surfaces.

Before you go on a business trip, you ensure that your girlfriend is not running short of quality bread.

Freshly baked sourdough bread.
A rectangular loaf of bread with a light brown, slightly cracked crust sits on a black metal cooling rack, which rests on a wooden countertop. The bread looks rustic and homemade. In the background, there is a cream-colored wall and a light-colored wooden floor.

When IT sucks, I often escape the world by just baking bread.
Two freshly baked loaves of sourdough bread rest on a cooling rack. The larger, oval loaf has a pronounced sourdough starter and a deep golden-brown crust. The smaller, round loaf features a striking star-shaped scoring pattern and a slightly darker crust. Both loaves exhibit a beautiful oven spring and an open crumb structure, indicative of a well-fermented dough.
