Parallella is the $99 Eval board for Adapteva's highly parallel computing chip that they have been recently funding under kickstarter.
The good news is that they have reached critical and even starting to take orders for non-kickstarters at the same $99 price point.
There is even a $199 version for the speed fanatics who want the Zynq 7030 FPGA from Xilinx rather than the 7020.
Either one is great value and looks like just the thing to experiment in the field of highly paraell computing and or that rather cool Zynq CPU.
By the way i've forked out and ordered one so watch this space
