A "cool", short, showy, encore-like, not-so-difficult, slightly-obscure piece

[frederic]

And is 20th/21st century.

Any pieces that best fit these descriptions?

[pizno]

How about a Scriabin Prelude?  Some of them are quite flashy, fast and big, and short.

The 2nd etude de virtuosite by Moszkowski is perfect

[etudes]

Poulenc Presto!
Takacs Toccata

[pianistimo]

saint-saen's toccata   (sounds like ragtime, actually)  the thirds are killers, until you get used to them.

[amanfang]

How about the 3rd prelude from Kent Kennan's Three Prelude's?

[stevie]

fazil say - paganini vars

[kreso]

Why dont you try Bemblee Bee in Rachmaninov's transcription?
It's not so difficult, it's very fast and atractive and the public always want to hear that!!

[whynot]

Medtner op 26 #2 (one of the Fairy Tale sets).  Molto vivace, 1-1/2 min long, visually flashy--goes all over the place.  Not easy at the suggested tempo, but exciting to play and hear, accessible to the listener (not "out there").  And pretty obscure.  You will definitely not catch anyone humming along.

[burstroman]

Allegro Barbaro, Bartok

[ted]

"Bucktown Buck" by Frank French

[burstroman]

"Malambo", by Ginastera.

[iumonito]

Stravinsky Etude Op. 7 # 4.

[pita bread]

Stravinsky Etude Op. 7 # 4.

Not so difficult?

[arensky]

Gershwin's Three Preludes, particularly #3; it's more obscure than the first two....

[iumonito]

Not so difficult?

Absolutely.  The thing practically plays itself.  I'd say you can learn it in 40 to 60 hours of practice.

Based on the time of year, there are many really good x-mas arrangements/medleys that fit that description. A few years ago, I heard a girl play a piece that sounded so difficult, but when she showed me the score, it was certainly sight-readable. (She had only played through it a few times herself.) I have no idea who the arranger is, though; it was some obscure dude that probably works for HL or WB as a staff arranger that no one hears about.
