Great little [pricey] graphics shield!
For NovaVGA - Arduino graphics shield
Soldered on some header pins, downloaded and installed the NovaVGA library for Arduino and away I went. Programming the shield with the official library is a breeze.
Additionally, I created a NovaVGA simulator library so I can try out various graphics routines ahead of uploading my code to actual hardware. It's here if anybody else is interested... https://github.com/ajbkr/SDL2NovaVGA
After calculating cost-per-pixel and especially after factoring in shipping and import charges, this shield does become rather costly for what it provides (160x120 output with 64 colours). A graphical LCD shield works out to be significantly cheaper if you only intend to mess around and you're not too fussed about displaying graphics on a large monitor (or TV paired with a VGA to HDMI adapter).
With respect to import charges, do check the tracking number provided against Parcel Force or Royal Mail if shipping to the UK; the USPS site updates stalled for a bit and I only learnt that import charges were due by entering the USPS tracking number I had been given into the Royal Mail Web site.
I have wired up a PS/2 keyboard to my Arduino Uno/NovaVGA set up. Probably going to make a simple raycasting engine and game, similar to Wolfenstein 3-D.
