Based base64 (now with more steganography!)
Summary
The article demonstrates embedding data in a base64 data URL by using ASCII art as a decoupled target image and a simple optimization loop to encode information with controllable pixel drift. It explains the near, but not exact, relationship between ASCII characters and pixel data, outlines a greedy approach for edits, notes rendering artifacts like a seam, and points to a public gist with code and live examples. It also emphasizes that the data-to-pixel linkage is not strict and invites further exploration with playful experimentation and demonstrations.
