Stripes is intended for practical applications - I use it to produce hobby-level circuits and prototypes. Over time I'll build up some examples.
PhorsePOV is a simple POV gadget which uses a single button to enter messages in Phorse code (a variation of Morse code centred around a phone keypad layout to make it easy to learn and remember). It's based around an ATTINY25 AVR running from its internal RC powered by a Lithium coin cell strapped to the back. The stripes version is shown on the left, followed by an actual build.
Feel free to build one yourself, in quantities of 1 it'd cost about £8.00 to make, or...
buy a complete kit for £8.34 (UK), 10.78€ (Europe) or $14.87 (USA) via Paypal using my email address.
The cost is a simple markup of 60% from what it costs me me to buy the components (excluding the PCB) if I buy in quantities of about 10, see DIY Drones for this principle.
3/6/2010: PhorsePOV was featured on Hack A Day and at least one person has decided to make one!
MiniPorch is a simple ZX81 back-porch circuit I designed for fun!
It's designed to fit in the PCB area of a ZX81 just to the left of the ROM and below the ULA:
It doesn't produce great images, but it's OK (note, black bands are due to CRT scanning, not the Back-porch circuit):
