Here is the Little Attiny ISP Shield can be used to Shrinkfy arduino projects, ATtiny ISP Shield makes programing AVR ATtiny bare Chips easy and simple and also helps shrinkfy your arduino projects Port your small Arduino projects to a low cost chip easily. ATtiny ISP Shield is a programing tool used to program bare for
8 Pin IC's like ATtiny13, ATtiny15 ,ATtiny25, ATtiny45, ATtiny85.
14 Pin IC's like ATtiny24, ATtiny44, ATtiny84.
20 Pin IC's like ATtiny2313, ATtiny4313.
28 pin IC's like ATMega8, Atmega128, Atmega328 using ISP header.
But, why just for a tiny?
Adafruit sells a shield (a bit overpriced IMO) but a nice quality ZIF shield: Adafruit ZIF shield
If one looks closely at the pinout of a 328P and a tiny85, one sees that the ISP programming pins are identical... only the power much be applied to different pins and the tiny inserted into the ZIF as shown in my modification: see pix
I use pin-jumpers, but one could easily install a switch for the purpose of applying power to the "tiny"
