When I started sifting through piles of old cards a few years ago, not really collecting mind you, just throwing stuff into different piles and boxes, the first thing that I became enamored with was the action shot where the ball is in play but not in the possession of any player.  Balls on bats, balls on fingertips, balls in gloves, balls floating in the air especially.  My first several attempts at Frankensets involve action shots.  I'm a big chunk of the way into my current set which is these Action shots ALL on a parallel or insert card.  So, no base cards.  If I see a cool shot I have to find out if there was a Silver/Gold Signature, a green border, a sparkle pink, a Target Red, a Wal mart blue, a Meijers purple, a yellow Walgreens or even an Electric Ice parallel.  Then if there is, I gotta go find it.  Which is why many of you got trade requests from me about some obscure Fleer or UD card from the Gold Medallion or Gold hologram variety, respectively, of such cards.  Lately I've been experimenting with dispensing with the numbers altogether and arranging a Frankenset entirely visually.  Some grand extension of all cards somehow connecting together from one to the next.  Still working on that, but I have a couple single pages of things I was working out ideas with.  

Every ball is caught by the glove but is still a cm or two from hitting the leather and having the glove actually snap closed and count as possession.  A split second on a nearly microscopic scale.

Start in the upper left corner and allow your eyes to follow the ball thru the cards like a backward 6 and watch how you end up in an endless loop around the bottom two rows.

Schrödinger's Baseball has just been pitched in the center card. Until the ball is hit every single play is possible all at once. It could be fielded and thrown to first, a diving catch coming in to steal a bloop single or a smash brought back into the park, or it could be a foul tip straight up into the catcher's mitt.  All at once.
