Chris Spackman’s NeoCities Page

Welcome to Chris Spackman’s NeoCities page

I loved GeoCities back in Japan in the 1990s, so was thrilled to discover NeoCities. I’m using this site mostly for educational tools and JavaScript experiments that I make for my schools and classes, and for other teachers and students.

Everything here is free to use. Please don’t hesitate to email me at chris@chrisspackman.com with bug reports, suggestions for improvements, or requests for other teacher-tool pages.

News

2026-10-11: The word game worksheet makers (Bingo, Word Search + Crossword, and Word Scramble) now let you choose the font, including Andika, which is designed for new readers, and the paper size, Letter or A4, for both printing and the Word download. Your choice is remembered on all three pages. Word searches, crosswords, and scrambles now take words in any alphabet: accented words like café and niño, and Greek, Russian, Japanese, and more. Hebrew and Arabic words run right to left.

2026-10-11: A big round of fixes across the site, mostly for text pasted from Word, PDFs, and web pages. Curly apostrophes, accented letters, and invisible characters used to be mangled or silently dropped on some pages. Printing is better too: charts, highlights, and answer banners no longer vanish with the browser’s default print settings, and more pages print on A4 paper. The command builders now quote what you type safely, and pages that could freeze on very large input now stay responsive.

2026-10-10: New: the Timeline Maker. Build a timeline right on the page from events, section headings, and notes, then show it top to bottom or left to right, full screen on the projector, or print it or save it as a PDF. Events can have pictures, with a description for screen readers and a line for the picture’s source. Choose from twelve color themes, all checked for readable contrast. Add more details and vocabulary words to any event, and in View, click an event to open it in a larger box, then step through the events one at a time. Students can save their timeline to a file to hand in as homework, and you can open it to show the class. For group work, give every group the same starter timeline; when they send their files back, Add from a file brings all their boxes together on one timeline, and you can choose whether to show which group added each one. Everything stays on your computer. Two examples are ready to load: the history of the internet, and a tour of the Solar System that starts at the Sun and travels outward, with pictures of the planets, moons, and asteroids.

2026-10-10: Copious minor updates, corrections, and the such on many files. No big feature changes, though.

2026-10-06: Updated the Bingo Generator to version 0.3.0. Type any number of sheets from 1 to 200, or fill the word list in two clicks with a ready-made set: numbers, number words, the alphabet, hiragana, katakana, months, colors, or shapes. (Remember to press either Replace list or Add to list.)
