... and use the "standard" libraries ?
But you'll find it hard to do with an Arduino, but a ZPUino will surely do the job (and much more). Like playing a Tetris game.
Video here: Easy VGA output on the Papilio FPGA - YouTube
Same IDE, same libraries (or "almost" the same), all open-source, hw design, IP cores and software included. All you need is a FPGA.
Cool, isnt' it ?

Wake me up when I can buy the Spartan-3E for the same price as the Arduino (Mega?):
Unless you know of a supplier of these boards (or similar) at that price already...
Other (and cheaper) options:
You can buy a S3E250 board, with FPGA + SPI flash and USB programmer/UART (FT2232) for US $50: Buy Papilio FPGA boards. The S3E500 is a bit more expensive, but IMHO is worth the money (USD $75).
GadgetFactory is also working on new boards, based on Spartan6 with integrated SRAM. Those will be amazing for sure, I haven't got my hands in one yet.
Even if they are marginally more costly than Mega, they do offer you other possibilities - one is you don't require that much external components (digital) for your projects. Disadvantage is lack of internal ADC - you can use a SPI one if you wish, and they are cheap and with very good performance (500ksps).
So, I guess is time for you to wake up

Hmm - well, I'll have to keep those in mind for future projects, should I need the capabilities - thanks for the links!
Very interesting! FPGA could be a future direction. I'll keep an eye on it.
Here's a VGA 640x400 12-bit color output interface, using an embedded VGA controller core.
This is the new Spartan6 board from Gadget Factory, with 512KB (4Mbit) 16-bit wide SRAM. The framebuffer is exported to CPU (memory mapped). Pixel clock is 25MHz, with 16-bit (4 bits are not used).
