The great and educational original project by @gregatku have been gutted, and all (3 blocks of) code were added by me. Sorry Greg, it just seemed like a fun idea ;)
Original instructions by @gregatku: Rainbow Lamp - Click the Green Flag to turn it ON! Thereafter Click Stage to turn Lamp Strobing Off/On. Move the Mouse to the top 40 px to change the Lamp's size and/or the Speed at which it scrolls the colours. Then watch for a while until you get bored by it. Then maybe check out my "Greg's Pen Art" Studio: https://scratch.mit.edu/studios/25184965/ where you'll find much more interesting stuff.
