1. Create a font of decent size that contains ABCDEFH (could be anything else too).
2. Create a copy of it and flip vertically and then move it around so that it connect nicely with the font from step 1.
3. Merge 1 and 2, then create copies of that and keep extending the pattern.
4. On a separate layer, create an egg-shape (or any other shape I guess, select border and fill it with black or another color).
5. Remove any parts that's outside of shape from step 4 from step 3.

I am wondering if I should create a plug-in that does this automatically and change up thet sizes and randomly order them too so that you get a different design each time you run on a predefined shape. What do you think?

1. Using the same method to get a design on a square (of mirrored and rotated letters).
2. Put pattern on step 1 on a white square.
3. Use Map Object - Sphere (use default settings) check transparent background then OK to get a sphere of mapped pattern.
4. Scale the mapped sphere down to ellipse (egg shaped like).
5. Put it on a nice background.

That's it.

Here's a video to document the whole process so you can easily create your own easter egg

Same techniques used on this egg just with color instead of pure black design

Here are some eggs using patterns generated by using the Text Pattern plug-in

using version of plug-in creates more repetition in design

Egg using v3 of plug-in (which allows user to specify number of maximum colors to randomly choose from).

Thank you Purple Bruce Lee (I mean Wallace).

And using the same plug-in for the pattern to use as sort of like stencil to cut out another image (in this case from unsplash); we have something like this

sample of version 5 (using as stencil for an unsplash image).

Combine this with wobble3D plug-in
to get something like it's organically painted.
