The following are demos by Ian Taylor available for download.
A more active list of hobby projects can be found here.
The Bee Demo is a simple maze game demonstrating Microsoft DirectX 7.0
graphics techniques. In particular, it performs relatively sophisticated,
real-time, soft shadowing.
Amongst other graphical features, the game demonstrates:
- Multiple, dynamic light sources;
- Coloured and attenuated shadows;
- Self-shadowing;
- Penumbra approximation;
- Silhouette optimisation;
- Mipmaps with tri-linear filtering;
- Bill-boarding;
- Alpha blending;
- Triple buffering;
- Fog effects; and
- W-Buffering.
The archive contains the final Windows executable, full C++ source and
documentation.
Update: Finally implemented a satisfactory
throttling mechanism (which greatly improves responsiveness) and fixed a
couple of minor bugs. [09-Dec-2002]

The Blox Demo is a 3D block-building simulation. It raises a number of
questions:
- Why is the executable so small (only 28 KB)?
- How can it render the 3D model without OpenGL or DirectX?
- How can it save a model as a standard thumbnail bitmap, but retain
the details of all the blocks making up the model?
The archive contains the final Windows executable, full C++
source and documentation (including the answers).
Update: Tweaked project settings to get the executable less than 32KB. [22-Jun-2003]

Flag Finder is a simple client-side, dynamic HTML web page that helps users
find a country given visual aspects of its flag. Try clicking the "Highlight the most effective question"
checkbox.
Not exactly rocket science, but quite effective nonetheless.
Requires Microsoft Internet Explorer.

The Map Demo is a demonstration of 128 different projections of a world map. It features:
- Dual-resolution, world coastline data in only six-and-a-half kilobytes;
- Arbitrary zooming; and
- The ability to save maps as Windows Enhanced Metafiles
The archive contains the final Windows executable, full C source and documentation.
|
The Curling Demo is another exercise in keeping executables small. This 56-kilobyte game features:
- Configurable computer opponents;
- Smooth three-dimensional graphics; and
- Sound
The archive contains the final Windows executable, full C++ source and documentation.
|
Version 2.0 of the Map Demo extends the functionality of Version 1.0 whilst still fitting in under 100-kilobytes. It features:
- Coastline and border data for over 200 countries and regions;
- Over sixty statistics and codes for each country;
- Vector-drawn flags for each country;
- 128 map projections;
- Choropleth statistically mapping; and
- The ability to save maps as Windows Enhanced Metafiles
The archive contains the final Windows executable and full C source.

Unifont is a simple client-side, dynamic HTML web page that demonstrates
packing of many bitmap glyphs into a single, small bitmap (128x64) to produce over 1000 codepoints.
|
Easter is an experiment in optimising the computation of Easter Sunday
for any year between 0 and 65535 AD using only Z80 assembly instructions.
|
|
This series of routines are the result of an investigation into the
optimal Z80 assembly instructions for performing 16-bit unsigned shifts.
|
Flag Factory generates a web page displaying 232 national and regional flags as scalable vector graphics.
It features:
- 16-bit MS-DOS support as well as 32-bit Windows console;
- A bootstrapping approach with no explicit file handling;
- HTML 5 and SVG 1.1 Tiny standards compliance; and
- Less than 16 kilobytes to generate over 330 kilobytes of display data
The archive contains the final executables, full C source and example output.
|
Version 3.0 of the Map Demo extends the functionality of Version 2.0 whilst still fitting in under 100-kilobytes. It features:
- Coastline and border data for over 200 countries and regions;
- Over one hundred statistics and codes for each country;
- Improved vector-drawn flags for each country based on Flag Factory data;
- 128 map projections;
- Approximate time zone details;
- Choropleth statistically mapping;
- The ability to save the data table as a CSV file (significantly larger than the executable!); and
- The ability to save maps and flags as Windows Enhanced Metafiles
The archive contains the final Windows executable (packed with UPX) and full C source.

To celebrate eighty years since the publication of Harry Beck's iconic 1933 London Underground Map, here's a smoothly-animated
evolution of the tube network through each decade using HTML5 canvases and JavaScript.
The maps are handcrafted vector graphics, with the scripts compressing down to less than 32 kilobytes.
|
At only 1017 bytes, Clock is a possible JS1K entry.
This is a competition for JavaScript scripts no larger than one kilobyte.

Based on a JSON database of nearly three hundred drinks, I drew up a Cocktail Venn Diagram of the major six ingredients:
- brandy,
- gin,
- rum,
- vermouth,
- vodka and
- whisky
These interactive web pages allows you to browse cocktails according to intersections of those ingredients, along with other groupings.
