I continue to revisit the kinds of things I did as a kid on the TI-99/4a computer through the lens of modern tooling. When I was a kid I used graph paper to create 8×8 grids, then worked backwards from that to create 16 character strings to represent those graphics.
Last night and this morning I created a reactive VueJS app that allows clicking on a graphical representation of the 8×8 grid, shows the individual binary slots as 1 or 0, and shows the individual hex characters (0 to 9, A to F) and allows a user to enter a hex string of 16 characters and see what the resulting graphic would be.
Along the way I use my JavaScript and CSS skills too.
