Mushroom Marvels

 Nervous System, 285 pieces. Another Patreon puzzle; this isn't my favorite cut style from Nervous System because I prefer the more unusual organic cuts, not this slightly more random version. 3/5

Snowflake Puzzle

Nervous System, 121 pieces. I liked the interaction of the more regular snowflakes with the curvier Nervous System style. 3/5

Wooden Chess Puzzle

 Nervous System, 378 pieces. Quite difficult because of how the squares are chopped up by all the curved pieces! 4/5

David S. Goodsell, Neuron Puzzle

 Nervous System, 423 pieces. Surprisingly difficult given the clear bands of color and different cutting styles--turns out there was so much variation that it actually became more difficult! 4/5

Jupiter Infinity Puzzle

 Nervous System, 260 pieces. The infinity puzzle is a lot of fun for me because I like weird piece shapes, unless I'm in a mood for fast progress, which this does not provide! 4/5

Eclipse Puzzle

 Nervous System, 248 pieces. This puzzle can be assembled in multiple ways to simulate an eclipse (but it is definitely easiest to do either the sun or the moon at one time, then rearrange. Really interesting/impressive design. 3/5

Big Bismuth Crystal Puzzle

 Nervous System, 267 pieces. A fun new style of cut from Nervous System; apparently the algorithm is the first they've used that generates dropouts, though mine didn't have them. Still, the highly irregular edge added a lot of pleasant difficulty. 3/5

Rainbow Puzzle

 Nervous System, 380 pieces. This is very similar to the geode puzzles in that the coloration bands provide clear assembly guides; maybe clearer here because the color is so strong. Would be a good intro to the cut style for those who might be worried about difficulty. 3/5

Möbius Marbling Puzzle

 Nervous System, 143 pieces. Based on the colors in a Georgia O'Keefe painting that were radically altered into a marbling pattern, this infinite puzzle was extremely challenging. The colors repeat but are not the same on both sides, which is also impressive! 4/5

Geode Puzzle

 Nervous System, 173 pieces. Small size makes assembly relatively easy since several bands of color usually cross any given piece, making it relatively easy to place in the puzzle. 3/5

Teatime

 Nervous System, 98 pieces. Cute small puzzle. 3/5

Giant Geode Puzzle, 59

Nervous System, 600-680 pieces (listed on box as range). Beautiful colors and once I actually got started it assembled pretty routinely, but seeing that huge pile was very challenging to start with. I think this might be like my reaction to Wentworths--1000 pieces is just too much for me to have peak enjoyment with the kind of puzzle it is, and I think I will stick to regular-sized geodes from Nervous System for the same reason. 3/5 hours of puzzling challenge; not too frustrating once assembly was actually underway

Baffling Bubbles

 Nervous System x Chris Yates, 212 pieces. Sugary Cereal color. Crossovers arrive to wooden puzzles (next up when I can get to it, the Par x Stumpcraft collaboration). I really enjoyed this--it has a lot of tricky connectors and somewhat deceptive color combinations. 4/5

Salamander infinity puzzle

 Nervous System, 216 pieces. What a delightful variation on the Escher puzzle--it is infinitely tiling but all the salamanders are differently shaped so they only fit in specific places. 4/5

Orbicular Geode No. 2792

Nervous System, 345-ish pieces. A lovely example of their geode puzzles, with the usual color banding and organic piece shapes. 3/5

Spiral Puzzle

 Nervous System, 166 pieces. Another puzzle with plain and blue identical half spirals; could have assembled it in any configuration but like this best. 3/5
