Blueprints
Blueprint from a picture
The picture becomes pixel art made of game blocks: a wall, a floor or a relief. Build it layer by layer from the bottom up.
Pixel art settings
A gigantic calculator for 10-bit numbers: it multiplies up to 1000 × 1000 = 1,000,000, and also adds, subtracts and divides with a remainder. The blue switches are number A, the orange ones number B (0 to 1023, highest bit on the left). Two purple switches pick the operation: off+off — add, on+off — subtract, off+on — multiply, on+on — divide. The answer lights up as seven big digits; when dividing, the remainder lights up below. Inside: a multiplier made of 100 AND gates and 9 rows of adders, a divider with 10 subtraction stages, a binary-to-decimal converter (the “shift and add 3” method) and digit decoders. The yellow screen at the top shows the whole sum: number A, the operation sign (+, −, × or ÷) and number B. It is set to 1000 × 1000 right now.

Block outlines are not drawn on very large builds so everything stays fast. You can still select a block by clicking it.
