Playground, design by Oskar in 1998, made by George Miller in 2004. Object is to move that disk around until you can remove it; it moves from pillar to pillar without coming off, and as you can see from the loop, there's likely a parity reversal involved. This is a large puzzle; 7" tall, but weighs only 8.6 oz. Buyer to pay actual shipping charges. Paypal payment, add 4% for fees.

From Recenttoys:Back in 1992 inventor Guido Lap came up with the idea of interchangeable strings. Ten years later Brainstring Original was introduced and almost immediately became a worldwide bestseller. To date, Brainstring Original is played in over 40 countries and people are still amazed by its seeming simplicity and surprised by its infinite possibilities. Most recently – after a couple of years in development – there’s a new, even more inspiring puzzle: Brainstring Advanced.N...

Rubik's UFO, not the easiest twisty-puzzle to find. New in package. Weighs 7.2 oz. Think it was made around 2005, though I can find no date on the box.

Rubik's Bricks, Rubik's Clock, Rubik's Triamid, all with original packaging. The Clock box is a bit crunched on one corner, with tape on the end-flaps, while the Triamid box shows medium wear, and the blister pack for the Bricks has been pulled off the cardboard backing. Instruction sheets are included with Clock and Bricks, and I don't think Triamid came with one (it's pretty simple; the instructions are on the back of the box). Total weight is 1 lb, 2 oz.

This is a combination sliding piece and hidden object puzzle. Place the 8 dominoes from the bottom into the space at the top by replacing the 7 dominoes at the top.This puzzle narrowly escaped destruction in the great Colorado flood of 2013!

This was Dave Rossetti's IPP28 exchange gift, in Prague, 2008. His accompanying sheet says, "Snakes in a Plane is based on the Rush Hour concept by Nob Yoshigahara. By using spiral pieces, Oskar made cheating impossible. Aubrey developed a special challenge that takes as many moves to solve as to reset... Production was done as a combination of 3D-printing and laser-cutting." He describes this as a Sliding Piece Puzzle.

Dustin 1935 (Laser cut plastic, 4.75" x 4.75" x 1/4"; base is 1/8" thick, tray edge is 1/8", thick and pieces are 1/8" thick) Looks like the Fifteen, puzzle at first, until you notice that pieces, except for piece 15, are joined together in pairs. Described on page 151 of Hordern's book, who notes that are a number of ways to solve it. The designer has made the pieces sufficiently tight so that solution is possible but not via Figure 4 shown in the Dustin p...
